Good stuff! I’ve been 8 miles offshore with one motor heading back and nothing better to do than diagnose the problem at 7 mph. It was a complete loss of power. Trim and everything! 115 Honda. 20 minutes later after going through the biggest fuse to the smallest it was....the smallest fuse that was the problem. 10 amp fuse shut the entire right engine down. I replaced that fuse 16 years ago and never had any problems.

I once blamed my wife for power loss because she gained too much weight. She hit me. Turned out to be a spark plug wire fell off. Anyway start your analysis with the engine not your wife.

Sound familiar 😅

Just got a marlin with a omc 115 took it out to find that at full speed the boat would fall on it's face . It was a rotten fuel line it was sucking air. CHECK YOUR FUEL LINES!

I just diagnosed this exact issue! 02 Vmax 150 carbd. I had Stuck poppet valve... removed calcification and greesed, also..5/16" ethanol damaged shredded line from primer bulb to engine was hidden in rigging trunk... upgraded to 3/8" (cut grommet at rigging trunk to make fit). Runs like a top now.

Awesome video with great content, thanks for everything

Was out on the lake the other day, and was running WOT when my motor slowed from about 6200 RPM to 5000 RPM. It would run at the lower RPM for a few seconds, and then speed back up. This happened several different times over the first 15 to 20 min. Then I ran around pulling kids on a kneeboard, so we weren't running that fast. After a couple hours of moderate speed boating, I opened it back up to run back to the dock, and didn't have any more issues with the throttle. I'm guessing maybe I had some water in the gas.

Good stuff !! Excellent advice for any boater...This is why I do a spring make ready on my boats, first mechanically and then cosmetically. Then I do a late fall post season Mechanical before I put her to bed. You can still have problems, even with all that, but it will definitely reduce the chance of it.

Was cruising on the river for a few hours heading to open water and all at once my carbureted Yamaha150 just fell on its face. If I tried to go above 2,000 rpm she’d shut down. Come to find out the fuel line in the rigging tube had turned into bloated jelly. That and the heat from the sun made the line collapse. My engine was trying to drink through a straw that comes with a kids juice box. All new fuel lines and she was back to running like new. The morel of the story is change those fuel lines. If they are a few years old it’s time.

Good info. I did not know the trim sensor would cause that. The plastic strap with positioner on the rod that the motor pivots on broke and the trim gauge wasn't working. I replaced it before taking it out. Yamaha 200 HPDI

The best engine tests for folks, thx a million. As a marine mechanic, those are valuable tips for most of the issues.

An issue I ran into with reduced power was my belt going out on my 175 verado. I lost half my RPMs at WOT and didn’t know what caused it. No overheats or change in motor sound, just lost power. Having a broken belt causes the supercharger not to run, just decreasing the RPMs. A new belt and she was all fixed up.

These video's are awesome! Great job!

Experienced the trim sender issue twice this week. Once on a verado and once on an evinrude G2. Glad to see you mentioned it. Completely ridiculous that this can put your boat into rpm reduction.

I found that a leaking fuel connector allowing air to seep in is also a very likely culprit. Check all connections frrom the tank all the way to the carb ... and be happy !

I forgot. Why did you make the decision not to make videos about I/O engines and outdrives? Always LOVE your detail.

Years ago I replaced a COIL on a inboard engine with another bad COIL . That’s right the NEW COIL was bad . I wasn’t familiar with the boat and thought the boat was just underpowered. Until I saw an arc while I had the engine compartment open . I replaced the coil again and thought I gained at least 100 horse power : ) .

I had this problem. Mine happened to me this one time when I was going full throttle and out of a sudden, I started losing power. The boat would not go over 7 miles an hour and whenever I would try to go over 7 miles, the engine would just die on me! Turns out, I had water in the fuel system and I think I know how that happened. I believe after I got some gas at the gas station couple of weeks prior, I forgot to close the gas cap, came home and washed the boat with the fuel cap open. That's what happens when you rush things and have millions things in your mind... -:) Better to take it slow and focus on what you do. After that experience, I check the water fuel separator every so often and also add some fuel stabilizer to the gas tank if I don't use the boat for more than 2 months.

This is gold...thank you again

Great videos do you guys have a shop ??

Loss of power 09 Verado, Supercharger band snapped so it was sucking air. Easy fix once I had a hose clamp the right size when I got back. They don't sell those on the water. I keep a couple on the boat now. Also had an issue when the prop hub spun. No problem, I have an extra prop ready to go on the boat. Oh yeah, you need a prop wrench to change it out on the water! They also sell those in plastic so they don't rust, just not on the water.

If you have a 2 stroke triggers, CDI’s and power packs will kill your power because they are usually running on half the cylinders. I’ve had this happen with evinrudes, mercs, Yamaha’s and even a Kawasaki stand up jet ski.

Was out on Lake Michigan, motor ran great, stopped, drifted, and then tried to restart, NOPE would not start, towed back to shore. Out of the water, went through the engine, fuel, plugs, screens, nearly everything, and all checked out, went back in, engine fully functional, never found the cause of problem, and never occurred again.

I literally took my bass boat out yesterday it broke down. Get on KZread today and see this video, maybe it’s a sign.

1. Run out of gas. 2. Prop falls off. 3. Stuck in reverse. 4. Locked in the garage by Greta. 5. Voted out of office.

Optis and verados, thermostats. Being able to read temps and water pressure is a big thing. My verado wouldn’t get up to temp and had low water pressure. Pulled the thermostat and sure enough had issues with rocks in it

Wish I had this video 6 months ago lol. I had the trim sensor issue.

Had a 40 hp carbed Yamaha run off a 6 gallon poly tank, on a 13 foot Del Quay Dory. Engine would idle fine out of the canal for the 10 minute or so run but after 2 minutes or so of wot, would die like someone turned the key off. Would start right back up like nothing was wrong. Checked the vent valve, nothing wrong there. Played around with it for little while and figured out that the fuel pick up assembly on the tank, the gasket had failed, so when we would push the throttle down, the fuel pump couldnt pull enough fuel thru the hose, because the gasket was allowing too much air into the tank, and not creating a little bit of a vacuum that the engine needed to run

@mr.cryptobull1520 nope. 6 gallon portable tank. What we think happened was over time the seal on the portable tank assembly went bad. The tip off was there was fuel under the area where fuel line plugs into the tank. It was all plastic. Put a different tank on it and the problem went away. At idle, it was fine, but under speed conditions the top would start to pull air and the engine would loose it's prime.

All the growth on the one hull can be power washed off? That was a crazy amount of sea life on that boat!

Would you know if a 2013, 90hp mercury outboard 4 stroke # 1B986113 has that trim sensor. Motor misses at idle and “bucks” when trying to get on plane, but no alarms. Motor has been at the dealership for about a month, they have ran fuel, electronics, compression and water test. They “think” it’s a faulty ecm.$$$ BTW, very informative videos

With this issue need to be sure the gas tank is vented otherwise negative pressure builds up in the gas tank and doesn't allow adequate flow to the engine. By simply turning the vent knob on the gas cap flow is restored and voila, problem solved!

Terrific , what about a power head ?

We have a 23 horsepower Vanguard on a Go Devil long tail that was loosing power because the hose that runs from the cylinder to the fuel pump was old and had a crack in it. I don't know if this is the case for the newer ones (ours is 32 years old) but it does not like to run on low fuel pressure. I'm not complaining when there's no problems this thing runs like its brand new but Id like to get one of the new fuel injected Vanguards and a new long tail. Unfortunately we do not have the money to buy a $5000 motor mainly because we just got a 1999 Key West 210 Bay Reef that is in immaculate condition for $6500. (it was a steal we got lucky)

Hey man what would be a reason that my rpm jump and down and the boat would lose power and die been kicking my ass change a few thing already if you ever had that go on in mercury optimax 200

Anyone have a recommendation on a good mechanic located in either the Ft Myers or Stuart, Fl area? Trying to keep the Florida boating dream alive while out of state. Engine is a 2005 Mercruiser 5.0 MPI, I/O. 260 hp. Thanks.

So my 50 Merc which is a 1984 revved fine on muffs . Has rebuilt carbs by me, but has sat I don't know how long as I bought it used. Has all new trigger and ignition module. took it out first time Saturday and it wouldn't rev up. I was running an old metal tank and 5/16 line. I went to the marina to buy a new tank thinking that maybe the pickup on the tank is clogged. The marina told me that my motor takes a 3/8 inch line and that my old tank is made internally for a 5/16" line and probably not allowing enough fuel flow. So I bought new fuel lines too. Not sure if the motor runs off just fuel flow through the main jets at full throttle or if the float level maintains a full bowl. I dunno I am stumped. If this does not work I think I will check for a clogged exhaust and if not that compression

I don’t know how you could have a boat with a fuel water separating filter that doesn’t have a see thru bottom sight glass

My Mercury 2 stroke 90hp 2009 3 cylinder will idle great at the right rpm. But when throttling up the motor begins to spit and sputter and begins to pop out of the prop exhaust. Waiting on jets. That what is left to change everything else checks out. In the video I see a round plastic screen. I wonder if I have one of those on my engine and where would it be located.

I take my bout out of the water at the end of the season to clean and wax it so its ready for the next season

I've got a yamaha80efi engine. which runs quite well. I have one issue which i cant seem to find the problem for. after running it for a good while and trying to get back to the harbour, it seems to have problems to stay in lower rpms. this problem does not happen when i leave the harbour. any ideas? greetings from Germany! :)

I had a power loss problem on my 2000 mercury efi. It would max out at 3500 rpms then jump to WOT out of nowhere. Found a loose hose clamp at the water separator. I suspect the small fuel leak was letting air into the system?

I have a 2-year old (220 hours) Mercury 150 4-stroke that has run flawlessly until about a month ago. Now, the first time during each trip that I accelerate to get up on a plane, the engine shutters as it climbs to higher (around 4K) rpm's' for a few minutes and won't reach max rpm's. After that, it runs perfectly for the rest of the day, even at full throttle/5500 rpm's, and even after stopping and starting. I use the boat about once a week and only use ethanol fuel. I know it's covered by warranty, but I like to take care of this kind of stuff myself. The fuel filter was changed at 100 hour service and it doesn't have a separate fuel/water separator. I'm wondering if it could be a venting issue.

​@@markdrabik9312 I thought I had found the issue...lack of good fuel tank ventilation. When I remove the gas cap, I get a very significant wooshing sound like the tank has a lot of pressure (or maybe vacuum). Based on some things that I read online I thought that might have been the problem but when I contacted the dealer who sold me the boat they said that my fuel system is pressurized by design and should do that. I did experiment with taking the cap off to release pressure when I was having the engine shuttering problem but it didn't seem to help. More recently I am wondering if the problem could be related to ventilation in the cooling system. I noticed that if I accelerated to plane from slow speed with the engine trimmed up too high, the engine would briefly ventilate. As soon as I hear that sound I trim the engine down but I get the engine shutter for a while after that. I'm wondering if the shuttering could be related to having some air in the cooling system and then the engine limits RPM's until it senses good waterflow. I've never heard of that before, but there does seem to be a correlation between those two things happening.
