if it uses a rear mount starter it needs a different flywheel or it will not properly line up with the starter and it will chew the teeth up.ask me how i know this,lol.

Or you can heat the ring and move it to the rear of the flywheel as I did

It is a bravo. The boat is a 97 scarab 22

If you can. Make sure to double check. I have seen my share of marine flywheels that you couldn't do that without having it machined. The ones from Jegs and summit almost never can.

Also you (the OP) may want to check with you balancer (you have to have the motor balanced) on what flywheel you should use. Just because the crank is internal balance you are adding longer rods and I assume shorter pistons and may throw the balance off by a mile. Just an example I stroked a 427 Tall block (all internal) and had to use 454 flywheel and balancer (external weight) lightened up some. It was a lot cheaper then them adding heavy metal by a mile. Also IMHO you should not use a fluid balancer because you are having everything balanced and a fluid damper is not a static weight.

I know how you know, because the same thing happened to me

Everything has to be balanced as a unit. Your machine shop should be able to tell you exactly what you need. I have built 496 with internally balance crank and the machine shop milled the weights off my external balance 454 flywheel. Good luck. That should make that boat fly.
