- Hello and thank you for stopping by! Thanks also for the support and subs! We are just ordinary guys who love playing with boats, cars, mowers etc so join us for fun...and disasters! In this episode I get to work on a junk Tohatsu 2.5hp outboard, is it too far gone? Thanks for watching!
Edited on Sony Vegas Pro 13.
It is not impossible that the piston rings are stuck in the grooves, you would probably have taken the piston out when the engine was disassembled.
We eagerly await more episodes. Compare compression with other similar engines.
New piston rings will probably do wonders. Do a compression test first, should be over 8kg.
A cheap way is to pour petrol mixed with oil into the spark plug hole, as the carburettor is probably clogged in nozzles. Modern gasoline barely lasts through the winter.
Feel free to use a nut driver directly on the flywheel and it will probably speed up. Just make sure you're pulling in the right direction.
It should be able to speed up don't give up. We are watching with interest.
You can borrow compression gauges.
1 7 2024 I agree that new rings will improve the chances of running....compression should be about 120psi.
Feel free to have extra fat oil mixture when the engine starts. Starter gas works in an emergency.
Hi, a wooden rod is much gentler on the piston.
Another trick is to heat the engine block in the cooling channel, then the piston is still cold and not expanded by the heat.
A third trick is to pour in a suitable mixture of engine oil diesel kerosene and perhaps gasoline into the cylinder and light it on fire, then the flame heats the cylinder but cools and lubricates the piston. Turn off the fire after a while. The heat difference causes the piston to loosen, use the wooden stick above. Good luck.
Hello there and thank you for your advice! Some really useful tips there which I will be sure to use next time I come across a seized piston! Have a great day 👍
If you are taking something apart you can, always take photos with your phone as you go so you have a reference when you put it back together again
@@skipperstan Aluminum absorbs heat, lightens and expands more than cast iron, this can cause it to stick even more when you have to loosen the piston.
Heating directly on the piston can also cause the heat to be transferred to the piston rings so that their hardening is lost.
It's easier to do wrong than right, you got the piston loose anyway. Congratulations.
@@seriksson9721 Thank you!
@@belacilaandmaja2510 That's a good idea! Thank you!
Fix this now or we might skip Skipper Stan. (Joke)
