95 502 MPI magnum in a 21 foot Scarab with a Bravo 1 HP drive. I am in the process of rebuilding the motor and trying to keep it reliable. I am installing flat top pistons. It has hydraulic flat tappet cam in it now, I'm thinking of switching to a hydraulic roller. Going with a straight thru hull exhaust, so water reversion should not be a problem. I do pull air chair, parasails, etc. Any recommendations would be greatly appreciated. Thanks.

hondatv,
Welcome to the board!!!.
A lot has been discussed about cams and such. Do a search on the T&Q section and look for threads on "cams". That should bring up a host of discussions on the subject..

Search is up at the top of the page..
Good luck.
