For anyone wanting to bomb around for more than 45-60 minutes on the water would highly recommend the external tank.

    I have a 5 hp sail power for my sailboat (basically the same motor with a long foot, lower pitch prop and smaller carb) and I didn't winterize it last season. This year it gave me lots of trouble by randomly stopping at full power or at idle. I took the carb appart and in a few hours I had it run like new again. I love the motor and I would recommend it too.

    Was just at a fishing camp that ran Tohatsu 9.8s. The camp had no dock, just a beach landing so we had to be careful to always tilt the motor up and drift to shore at days end. Hunters were also running them in super shallow water and sand/silt was getting sucked up the intake and actually blocking the outlet where the water jets out of the motor. Was a pain to get at and clean out that exit nozzle. Was odd that it was a small enough exit to allow sand and even tiny rocks to build up there and block the exit. Once that exit was cleaned the water exited just fine, so the impeller was still functioning. A lager exit hole would make more sense. Guess the bigger issue is that that same sand/grit will eventually bugger the impeller.

    I've got one of these (2015). I would agree with all you have said. A couple of tricks I've learned.1) I ALWAYS run some Seafoam in the fuel. it cleans the carb and stabilizes the gas. I use a 3 gal tank and never keep more than 2 gal in it. It's best to keep topping off with fresh fuel every other use vs run on old stuff. 3) The motor is harder to start 9especially cold) if you just yank the cord in a traditional way. Per the owners manual , it is best to pull the cord slow for 10-20" or so to run it through a decompression /priming cycle, then pull hard and short when you feel it comes to a hard stop near the end. . Sounds weird but it will start faster and more reliably this way. BTW, my 15 hp Tohatsu is exactly the same way.

    The reason it is hard to start is the position of the carburetor because it is so high up on the fuel tank it requires those extra poles in order for the fuel pump to pump the fuel to the carburetor Which is higher than the fuel tank itself this is a very poor design feature from Mercury if you don't want to have those issues and look like a fool with a brand new motor on the dock pulling it to feed gas to the carburetor then buy a Yamaha everything is positioned where it is supposed to be

  • @Skinnyriver

    @Skinnyriver

    11 ай бұрын

    Some possibilities: If it was hot, external tanks can build up pressure and cause too much gas being sent to your outboard, causing it to flood. Newer external tanks don’t vent out pressure like old tanks. Once a motor floods it’s hard to restart Have you tried to restart it since then? I would try to take it out again just using the internal tank. If it doesn’t happen again it’s something with your external tank. If it happens again with the internal tank, then you may have a fuel filter issue (dirty), thermostat issue, or a fuel pump issue. If it’s not the carb, then it’s probably a fuel flow or temp (running too hot issue) Try to isolate the issue to something and that will help understand root cause Is your motor a newer one or an older one?

    Thanks for the view!! Inflatables are generally a bit slower and harder to plane than a Jon boat. If you are planing out really well you may be tapped out. I’m actually now only getting 16-17mph (have no idea why 😂) maybe my prop is getting a bit chewed up. You could try a larger pitch prop BUT it would hurt your power and planing performance. Other thing is to experiment with your trim position. If you are dragging your bow increase your trim, if your bow runs high then decrease trim position. If you struggle to plane you could try LOWER pitch prop or maybe a hydrofoil. Good luck

    Have you changed the oil since the break in procedure? If no, then it’s probably just from the break in process. If you have changed the oil since break in, then I would change oil again and take a sample to make sure there aren’t any noticeable shavings. More than likely it’s just because it’s new but I would document it and send any pics/concerns to the dealer so it’s documented if you ever have an issue.

    Before you do take the carb apart, just pull out the gas intake hose and spray inside carburetor cleaner. Wait few hours, make sure you have new gas (drain the old one using the black screw at the bottom of carburetor). Put back the hose and start, if is cold, yes you need the choke, if is warm you do not need it much. Please read the manual. At the storage section it is stipulate clearly the gas with alcohol in it will create gum and a sticky admission valve for gas. Do not store the engine with gas with alcohol in carburetor, it will gum out (Thanks to the Eco-Freaks for adding alcohol in gas). That will prevent starting and running in idle or load. After each use the best is to consume all the gas from the carburetor, leave it dry. Sea Foam marine it is also a good gum cleaner, add it to the gas.

    That is weird. Is it planing out really good? Mine will only reach 3/4 rpm if it’s struggling to plane out then will “break loose” if it planes fully. Maybe try a couple different trim positions. Also check the prop, if the prop is chipped a lot then it can mess with RPMs and power. I’m not aware of any design issues that cause this but it doesn’t sound like a fuel issue. Some motors have a rev limiter, it’s possible it’s causing the motor to limit out

    Usually that means you need to clean the carb. Maybe some build up in there limiting the gas getting to the motor. That’s probably why you need to the choke so the engine pulls in more gas. You could try running some Berryman b-12 through it. That stuff really helped my other motors run better with out tearing down the carb.

    That’s a new one for me. Does it only click when you pull the pull cord or after the motor starts? Will it start? Is it possible the shift linkage is slightly out of place and it’s slightly in gear? Do you hear the clicking when the motor is running and in neutral? It could also be the safety mechanism that prevents the pull cord from pulling out when in gear. That issue is also cause by shift linkage sightly out of place

    I have the 2015 mercury 6hp 4stroke I bought used Let me make it known this is my first boat motor and I’m learning but I noticed the first time taking it out that when I put it in the tilted up position that it was leaking oil but only when I tilted the motor up only saying that cause I was using it all day no issues but when I went to load the boat up I tilted the motor up and that’s when I noticed the oil leaking down the shaft could it be a seal or lower end oil??I checked the engine oil since and I see no difference and I took it out the other day and I was having a issue that when I was at max rpm going down the river it felt like it was slipping out of gear idk I’m really new to boat motors and boats in general any help would be extremely grateful

    When you lay a motor down it has to be laying on the tiller handle side or oil will leak. That is probably what happened is it was tilted to where it was basically laying flat. Make sure when it’s tilted all the way horizontal that the tiller handle side is pointing down. Regarding slipping out of gear, mine does this sometimes and it simply the prop losing grip in the water. This happen a lot on the gal because leaves get caught in front of the prop and it causes turbulent water at the prop.

Spark is is looking good but motor wont even promise to start.. now i have bought new sparkplug to try it out on thursday evening.. do you guys have any tips or tricks for that?

    Definitely check a new spark plug, did you check spark with a spark tester too? Spark plug could be good but still get no spark. I hate starting fluid but you could try using a little starting fluid, if it starts on starting fluid then you know it’s not a spark and probably not a compression issue. Main things it could be Bad gas No spark or bad plug Fuel air mixture screw on carb is not set right Even though you cleaned carb, could still have issue with idle jet Choke problem Carb float problem (are you sure it’s not flooding?) Fuel pump (but it sounds you have ruled that out) Honestly it might be worth taking it to a shop for diagnosis at least.

    I have the exact motor. At half to WOT there is a bit of smoke that comes out of the front of the case. Doesn't do it idling or lower throttle.

    That’s weird, I’ve never noticed that with mine. There shouldn’t be exhaust or smoke coming from under the cowl. Is it possible it’s oil on engine block and it’s smoking off when the motor gets to operating temp? I would wash/wipe the block down and see if it helps. If that doesn’t help, I really don’t know what would cause it

    When you say cannot glide, you are saying it won’t plane out? A friend is mine has an inflatable and had to get a lower pitch prop. If the motor is running well and hitting high full throttle RPMs, it’s more than likely not a motor issue. Really 2 things, put it on a lower trim position, put more weight in the front, look at getting a lower pitch prop.

    Always when starting the outboard for the first time on any day... fill the internal tank to overflowing with the outboard in the down position as if it was in the water and running. Gravity is a beautiful thing and the carb HAS to fill as the top of the fuel tank is above the carb level. (This technique also starts Briggs and Stratton flo-jet carbed (on top of fuel tank) lawn mower engines... With the tank full to overflowing every fuel passage is filled before you start......and it then starts so easily...... Add a squeeze bulb into the line from the internal tank to the carb??? Fit a separate one way flow valve between the internal tank and the fuel pump? (if the one way valves in the fuel pump don't work...back them up).

    Yeah usually that means too much air. There is an idle speed adjustment screw on the carb which changes the fuel air mixture ratio. If it’s a newer model there is sometime a brass cap over the screw. Just fyi it can void warranty if you pop the cap off and adjust it. You can also look at changing the idle jet size (get an idle jet with a slightly larger hole/orrifice size)

    @CarlosGarcia-sf4gx maybe but usually a loose prop nut only result in a lot of vibration. The prop nut holds the prop in place on a spline gear. If that spline gear wore down (because of the loose nut) the motor RPMs would rev through the roof and the boat wouldn’t go anywhere

    @CarlosGarcia-sf4gx there is a rev limiter on some Tohatsus, so if your prop is slipping then you could be reving RPMs too high and the rev limiter is kicking in, basically bogging down the motor. Does it bog down if you rev the motor in neutral? That would be a good test

    Tell ya a trick which contridicts you saying about keeping the gas tank full and about the carborator.... Gas that sits in a catborator always goes bad so if you dont use it all the time dont leave gas in it run it on idle till all the gas is gone out of the motor no gas in it your carborator isnt going to gum up ..... That simple...

    Yeah I agree, but the cold starting issue isn’t only when it sits for a long time. It can be the next day, so to keep it primed you need to keep the system full. But totally agree, I run it dry if it will sit for more than a couple weeks. There is only a little gas in the carb so it will evaporate and go bad fast. It’s not a bad gas issue, it’s a prime issue.
