I am running a os 81 marine on a 36' AEROMARINE CAT.
I am having starting problems [under powered belt starter]
I was wondering about changing to heavier flywheel on the engine.
I have a steel one that will replace the aluminum one.
I thought the heavier one would help spin start better.
Have added weight to electricstarter pulley to help pull thru comppresion.
I realize I will be sacraficing acceleration.
I was wondering the pros and cons.?
Thanks

ps I don't race

boatnut , I've heard of guys bringing a propane torch. They heat the top before starting. Or look for a heavy duty starter. 24 volt is best. I've got a .12 NIB Nova Rossi that's giving me problems on the start-up. I put her away for the winter. Once broken in no problems. Keep on it.

You're going to need 24 volts to crank it over decently. Loosening the glow plug a little while cranking it over will help somewhat.

Keep the current flywheel ... And switch over to 24 volts like everyone says ..... Switching over flywheels could be more of a headache in the long run if not balanced properly ....
