The problem with my very good 1978.. 235 hp 2.448 liter was that the piston rings got stuck in the pistons.
There was two types of pistons available from OMC, one where the rings was close to the top of the piston..and one where the rings was a little bit down from the top..
Did not matter..the piston rings was stuck after only a few hours racing..
To make clear..the piston rings was stuck in the pistons from carbon build up..
and we lost some speed from that..
The blown powerheads was "connecting rod out"..!! at high RPM..
There was a balancing driving style..
The very light built ARGO cat was extremely fast..
but we could not find big enough props to hold the RPM down..and it is hard to back off to keep the engine alive..in racing...
