Trying to choose between the REMAN PLUS, 357 MAG BRAVO 4V (BRAVO 3) or the 350 ALPHA MPI for a 28' Mariner Flybridge, any advice?

a 28' Mariner Flybridge

Big block.

I put two new Bravo 357s in Our 31' Chaparral. A significant performance increase over the original 260 HP engines.

I personally wouldn't put a small block of any kind in a 28' flybridge boat, unless it's a really light boat.

Unless there are two of them, I am with mkast and DonS. Big block required. And if there really is only one engine/drive NO WAY would it be an Alpha.

But i am guessing there are two of them. In that case you have a hard decision to make. The ease of starting the MPIs or the better manueverability of the B3s. I would choose the B3s.

If you have a twin set up, why not run 350MPIs with B3 legs?

If it's a single, go big block...

...

I am guessing that it's a price thing. I'll bet you a nickel that the remanned/carbed 357 w/B3s are the same price as the 350MAG MPI with Alphas. I am certain that 350MAG MPIs w/B3s are going to be MUCH more expensive than either option he's presented.

Cost is a consideration the two options presented are a similar cost, the only other option available is a 383MAG STROKER with a Bravo 3 but this is a lot more expensive and I must admit I do not know the difference. The mechanic did not present this as an option?

Steve C, JUST ONE ENGINE??? Really?????

I think we have established that the boat has one engine, it will be used predominately for cruising the river with the occasional off shore trip.
I joined this forum for assistance to tap into the collective wisdom of people in the know. If anyone have constructive comments I would appreciate it, if not I apologize for any inconvenience.

Your mechanic is not pointing you in the correct direction, then. A small block V8 in a true 28' flybridge cruiser is not a good match. It could be done, but I'll guess you'll always be wishing you had more power.
