Outboard valve clearance adjustment

In this video I check and adjust the valve clearances on my Honda 40HP four stroke outboard. This involves removing the valve cover and using feeler gauges to measure the gap when the piston is at top dead centre.

    We used to describe it this way: It should feel like a little bit of "sucking". Good to have some oil resting on the metal. Additionally it won't hurt to try the next bigger and next smaller size of gauges if you are not sure. If one of these fits, too, you have to check again. Especially with the exhaust valves where temperature is critically.

    Ah brings back a story to share. I had a 65 VW that fire burned up the side of one of the plugs and ruined the head. I also had a 68 VW bus that the crank broke. I took both heads off and put them on the bug. Went to start it and the rockers all were too tight and stopped turning the key since there was no compression with all the valves open. no damage so gave up and went back in the house to think. Then got an idea💡. I went back out and got a hand full of washers and raise all the rocker assemblies up and set all the gaps per spec. It worked and there was allot of🍺 to celebrate. my brother bought it and ran great for years before he sold it still with my washers on it. Moral of the story once a hack always a hack. haha

    50:1 is easy, in litres. What ever you put in the tank, in litres, double it, add a zero and put that many millilitres of oil in the fuel. So 25L of petrol x 2 = 50 = 500mL of oil. For 25:1 you multiply x 4 25L of petrol x 4= 100 = 1000Ml of oil ( 1l) For 32:1 you multiply by 3 25L x 3 =75 = 750mL of oil.

    Hi Stu, I appreciate your videos, thanks! I'm trying to fix an issue that I caused on my Yamaha F40 outboard (4-stroke). It's already cost me $800 to the Yamaha dealer who thought that cleaned the carbs was the problem but I was sure it wasn't. Retuned the engine no better off. What happened was, in a momentary lapse of reason, or due to lack of experience, I cranked the engine with the timing belt off. I know .. I found out later this is a big no-no. Do you know what problems does could have caused? After doing this the engine starts and runs okay, but has about 80 per-cent of power at full throttle and sounds quite ragged and noisy. From what I understand I might have bent a valve or something. Any help or suggestions you can give me would be appreciated.

    Hi Russell, yes, bent valves is common as some of the valves will be open and therefore hit this piston. I would take the head off and check all the valves. The easiest thing is probably give it to a machine shop and get them to resuface it and grind the valve seats at the same time. It will be better than it was before the accident if you get that done.

    What does it mean if I have my settings to t1 tappets have play like in your video however cylinder 2 intake has play too but the exhaust valve doesn’t move. Cylinder 3 intake is tight and the exhaust side has play. Also I can move the crankshaft by hand is this ok(I have carbs off too)? Thanks

    Hey mate thank you so much for all the knowledge you sharing I would like to ask you a question. Can i use the carbs from a 150hp two stroke jonhson on a 115 hp same year. Would that cause a problem on the smaller engine??

    I'm not sure if they are the same, but if they are the same part number you will probably find you need to put smaller jets in to keep the air / fuel ratio correct.

    For newer readers like myself, it's worth noting that if the carb intake diameter is too big the air velocity could be too slow and not suck out enough petrol, too small and you can't run at full speed as the engine will be throttled

    I think my Yamaha fourstroke 115 also need to check about those valve clearance because it had been 1400 hours now. By the manual said to be adjust every 1000 hours as I remember. But it was a DOHC beside of SOHC shown in this video. I am not mechanic but just learn so much in your video, is that any tips about fine tuning the DOHC engine valve clearance? Or just need to look clear about those intake and exhaust direction and then good to follow your instructions? Thanks!

    If timing marks are not available securing a micrometer through the spark plug opening and watching to see when the deflection of the needle stops moving and then starts to move the other way is a good way to determine TDC.

    With 4 strokes as long as the piston is TDC (shine a torch through the spark plug hole, watch the piston. when it stops moving up or down, its close enough, 5 degrees either side makes no difference) the rockers will be on the back of the cam and the gaps can be set.

    Bigger is better than smaller. If the gap is too small the valves won't close properly and you can lose compression and burnt up the valves.

    Exhaust valves have hot gasses and flames around them whereas intakes have cooling petrol round so they run cooler hence the bigger exhaust gap

    Could be that it is lean. Does it have a choke that is on? Are the carburettors clean? If that is all good then I would start to look at the reed valves as well.

    Hi Stu, suggestion for you. One is how to transport a old 2 stroke kicker motor in a car and be able to start it with a dry carburetor? Seems to be an issue with my son's merc even after pumping up the fuel ball but finally starts after many pulls. The choke works fine once the carb has fuel in it.

    It is generally the same for all four stroke engines so you'll be able to find some good vids on it, but the basic idea is to make sure the piston is pushing air out the spark plug hole so you know it is on the compression stroke not the exhaust stroke and then put a straw or something in the spark plug hole so you can see when the piston is at the top of it's travel.

    Hi Ryan. Sounds like you are on the money if the carburettors are closed all the way and the idle is still too high. It is either going to be a vacuum leak the timing too advanced. Not sure what it should be set to, but I'd put a light on it now and see what it is then move it closer to TDC (presuming it isn't already ATDC) and see how the idle sounds.
