Good evening,
I have a new to me 1997 Sea Ray 230 overnighter... come to find out it has a cracked block and I need a long block. It has a 5.7lx vortec alpha one gen 2 drive.
I'm debating on what to do and want to order the motor tomorrow. Should I buy a rebuild from someone that claims its a marine engine, bigger cam(roller), and better pistons.(2 year warranty). Or buy a new long block from one of the several people I found online? Or should I buy a new or rebuilt 6.2 longblock?
My first issue is the electric fuel pump being needed. I currently have mechanical and would prefer to keep it this way. Are there new block available with the mechanical pad?
2nd can the alpha drive handle the 6.2? I mainly cruise around 3200rpms don't beat on the boat too bad but do like to pull tubers and some short wide open runs.
3rd quality I don't know who to trust. Lets face it on the warranty... unless its doa there pretty much isn't one. There can always be some excuse for them not to honor it. (bad mixture, bad install, timing wrong...) Are the gm marine long blocks good? Reliable? like my last 1986 305 block was? Or is it better to get rebuilt and know which components were used?
Sorry for the long story and any advise would be appreciated. This is my first repower and I want the best bang for the buck. Fuel usage isn't a concern, costs go from 2300 reman 2900 new then 4000 reman and 5000 new for the 6.2. Goals would be to break 50mph if possible, and be able to cruise at a lower rpm due to more power.
Anyone hear of raytek marine? Hes saying upgraded pistons/cam longblock for 2800 and claims 370+hp?? is that possible with a cam?
Other options are marine power, michigan motors, rapido and center state engine builders.

... The extra 20 or so ponies will add a few mph (maybe 3), but that's all. A few pennies to the pound of better fuel economy, but not near enough to pay back the extra...
