Need help with cam selection!

Well guy's I have finally got the the money together to finish my boat project! Thanks to the IRS. Gotta love the tax returns. Just ordered a master rebuild kit with a B impeller, Ride plate kit, and a manual trim lever. I also have secured Set of high performance heads, Performer RPM intake, MSD ignition system. I am know looking for a cam and am open for suggestions. I am still debating on exhaust not against headers but would like thru-hull headers. I would like to get the most performance possible but also don't want to blow the engine. Tom at jet boat perf. Said that if I am going with thru-hull That I should stay below 235 @ 50 and suggested the comp extreme marine cam. He said if I go higher than that I run the risk of sucking water in the exhaust valve. At least that is what I got from it. Do I have to go with a marine cam?

Thank you I will try that.

glad to see you back at it

I'm with Tom stay below 240 @.050 and yes stay with a marine cam.
I would call Comp. and tell them what you have. They will put you on the right track.

Thanks for all the help!!! I will Keep everyone posted. When will you guys start getting your boats wet?

I'm still puting my motor back together

Should be mid to late April

If you need any help with your pump give me a call

I am sure I will be calling you!

They are steel heads. Angle plug. 200cc intake runner 64cc chamber 2.02/1.60 valves. I don't know what the compression is. Engine has stock bottom end. I have decided on using OT headers.
