I want to take the flywheel off to clean underneath it. Looking in its caked in old grease and it just doesn't look good when you shine a torch under there? It would be good to check. Will I need a flywheel puller and strap wrench or is there a way of getting it off with just removing the socket?

You can try but your'll almost 100% need a puller, any car garage should be able to pull it off for you if you have it prepped for them

Nope, once all cleaned off just lightly grease it and torque it up

Happy. Just have to find a clanky. Hopefully I don't find any disasters under there.

Managed to borrow a universal puller. It's one of those claw looking ones. Not the screw in bolt type. Hopefully it will do the job. One way to find out!

Well that was scary!
Found this underneath. Looks quite dirty. Worth replacing or just cleaning up?

Just as a curiosity question. What is it that hold the flywheel on so tightly that it needs the puller. Once that nut is off I can't see anything that was holding it on. Why doesn't it just pop off once the nut is removed?

If you've got the flywheel off it's worth removing the lighting could if it's on a thundercat, gives you slightly more crisp acceleration and a bit of top end

Put the fly wheel back on and taken the boat out now. I've had it going well before now so I don't feel like I need to go removing it again. Though the boat wasn't accelerating well today and top end was low but I think that has something good to do with something else. Video to follow, I'll edit out the boring bits.

Here's one video i took of the engine running, i had a go pro on the top the whole time so i'll edit and post that at some point but for now can anyone think of something not right with this?

The top speed i got was 18 knots so that's well short of what i had the last time it went out and ran well. the problem was the following day it had no power.
the boat has done double this speed in the configuration it is in now so its not engine height or props that's the problem for now.

on the plus side i think its running quite reliably now at this slower speed but there's more in there somewhere.

sorry for poor filming, i was looking forward and had arms crossed and all sorts it was a bit awkward.



and one of it running on muffs after the run.
https://youtu.be/OZHQ0RzXM0E

Plugs were wet when i took them out after the run out at sea, would indicate running rich? how can I make it run leaner as I'm running the "correct" oil fuel mix (50:1)

Doesn't sound like your reaching WOT what RPM are you getting

I have a tiny tach but can't get it to read rpm must have it on the wrong setting or rigged wrong but it just reads zero. Followed the instructions but no joy. Will have to try again. I have no doubt the revs are low however, at a guess it's not getting above 4k and that's generous, in neutral it revs past that so it's while in gear somethings not happening.

Get the tiny tach working first and go from there

I'll have another go fitting it tomorrow. Might be able to get another run out of it Monday. I want to try a new set of spark plugs and see how that goes. I could try tomorrow but can't really do anything different to the engine.

Boat Motor Kill Stop Switch & Safety Tether Lanyard for Yamaha / Tohatsu / Honda Outboard Motors https://www.amazon.co.uk/dp/B01IR075..._2btCyb4JF8W77

Hope that link works.
Also found out today the kill chord or switch then only sometimes works! Less that ideal. If the chord is pulled sharply it normally cuts out but pulling it off slow is keeps running. Either way it's unreliable and needs to go! Will the above switch fit fine?
