So I bought this 1998 Baja Islander with what looks like more of a truck motor than a marine motor with a super lopey cam. My question is if this setup likely to cause me big troubles in the near future? I've done quite a bit of searching but the exhaust style seems to be more important than the actual cam specs.
The cam:
"THIS CAMSHAFT IS A HYDRAULIC LIFTER GRIND .576 LIFT 246 DURATION @.050 ON BOTH THE INTAKE AND EXHAUST AND IT IS GROUND ON 108 DEGREE LOBE SEPERATION. "
This is the motor as it came off of ebay. It seems to be a cheap hot rod build as I hear the Pro-Comp heads aren't that great.

My exhaust setup:

Thanks in advance for your input.

What are my options here? If I switch out the cam I may as well just find another motor since I have to yank the whole thing out anyways.
Different exhaust? Move the water inlets downstream?

Ground at 108 is not for a marine engine, need to be at 112 with wet exhaust. If you are 100% dry to the / out of the tail you can run that type automotive cam grind. Best to get yourself to a good marine engine guy for some solid advise.

Got it. Thanks for the input. This thing would make a pretty bad ass V-Drive motor though! I'll see if I can find a buyer and source out another engine for it.
Where's the best place to look for a used motor? I've looked in these classifieds but they seem to be mostly new super duper builds.

I found a good tuner here locally that could probably swap out the cam for about $1500 and he thought the rest of the motor should be good enough for use as a ski boat with no problems, so there it is. Thanks.
