New Addition

Here's a few pics of the boat that I recently purchased. It's a 1998 28ft Carolina Classic. It has twin Volvo's 7.4's (454). The engines have suffered from the typical water injestion problems. The Starb engine runs good, however the port engine has issues. That being said, I got it for a good price. The hull is in excellent shape, and I feel that I can fix the engines along with coming up with a fix for the water injestion problems that this generation engine is plaqued with.

as for the injestion problem be sure your exhaust elbows are at least 13 inches above the waterline at rest and the hose is angled so there is a 1/2 inch drop for every foot travled. nice find and great boat, the injestion problem was very common with the CC 25 the 28 wasnt as bad but still had this issue.. working at a marina in hampton, va, the above info is how we found to correct the problem. also try to avoid extended periods of high speed backing

It appears that when they went with the fuel injection engine they went with a roller cam which has a good amount of valve overlap due to a tight lobe separation. As a result when you let it idle for a long time it will eventually suck water vapors through the exhaust. I spoke to Mac with Carolina Classic on this matter and he said that before I shut it down to run it at 1500 RPM's in neutral for 3 min then shut it off. This will dry everything out and I shouldn't have any problems. Also I plan on putting a cam in that has a wider lobe separation which will in turn have less valve overlap.

Thats a really nice hull!

I'm not a mechanic, but this makes me think of the postings earlier this year regarding exhaust manifolds in their design flaw which allowed back of water, eventually reaching the engine. It might be something that is pertinent to the current conversation. As I said, I'm not a mechanic but...

MERCURY, HAD SIMILIAR PROBLEM WITH THEIR I/O, and they also recommended to run at 1500 rpm's for three minutes. That I think, would help all I/O's of dryingout the system out before cutting engine off.

No surprise there Steve. Congrats on the CC! Not many complaints on seakeeping abilities.other than roll moment. But hey, it needs the deadrise in those and other cuts.

Thanks guys. This boat seems to be built like a brick sh$t house.

I was told that it has over 1" of glass in the bottom. Wet weight is around 15,000 lbs. My 2001 GMC 2500HD Duramax Diesel (Big Red) didn't want any more!

NICE boat!

Not to hijack the thread (well maybe not too much), but do any of you guys now if the water ingestion problems of the fuel injected big blocks were also found in 5.7 fuel injected V8s?

thanks
