I am debating pulling motors or doing top end and cam change in boat. Just got boat, it's put away till spring and was wondering if anyone has changed cam in forward motor by removing back seat.Don't know if it is removable? Not going to drill hole.

Thanks Joe

Forward motor will have to be pulled. Engine compartment front wall is fiberglass. There are actually two walls, the inner for the engine compartment and then another which the seat bolts to.
Would like to hear your results if you do the cam upgrade. Others have dynoed at 860 with the 700 cam and the ECM tuned.
Hope to see your boat at Buffalo Poker Run.

Thanks for reply, better way to do top end anyway's, myself and some budies are talking about run, hope to do it.
Ran stage 2 for 10 hrs near end of season, but doing top end anyway's might as well do cams to let it breath.
Thanks again

What speeds are you getting with your 38? There are not many 38s with the 600s. I would do the upgrades to get some more hps when you have the compressor anyway!!
