hey can anyone tell me how to start the engine on mu boat, its an old OS without pullstart and its for planes, i usually use car engines for my boats, So how do i start the damn thing because ive been trying to check if everything runs good but nothing is running so so much for that...

Can you take a picture of the engine area of your boat and post it here? Engines in boats usually have a flywheel. On the flywheel there should be a groove. A starting belt will fit in the groove. Then you use an electric starter motor at the other end of the belt to turn the engine.

this is the picture of the exact same model .30 OS engine with all the same hardware, dont mind the make shift water cooler...

oh right thanks ron olson

oh and allso, how can i make that starter or do they sell them?

You should be able to find them at an R/C shop. It's basically the same as the starter for planes. You need to be sure you get one with a metal starter cone and the cone needs to have the groove for the starter belt.
