Default 370ss and 400ss 525

hello,

looking for some input. Just sold my 330 with 496's and looking to go to a 370 or 400 with 525's. What is the cruise speed on these boats with this power? I've looked everywhere and can't seem to find that info with 525's? I do most my boating on lake st. Clair and may go an occasional longer run so fuel burn isn't really a concern? I know the 400 tops around 62 but what does the 370 top at? I also have seen a few fountain 38ec's with 525's that claim 70 top and 50 cruise but I think I prefer the formula for size and finish in addition to the walkthru windsheild. Any input would be appreciated.

Thanks in advance

Yes, I've heard that, but I also heard that no hole shots and drive showers they will live? I would buy the diesel d370 package before I would do 496's.

My D-6 350 volvo 400SS comes out of the water quicker than the 525 bravo 3 boats. I have run both of them extensively. The low boost mechanical blowers over turbos must have something to do with the bottom end torque?

Fossil fuel. I'm not completely opposed to the diesels, there are quite a few d370 boats floating around for sale. I have read the diesels accelerate faster just run out of steam up top, which how often are you really putting the sticks to the dash? Yours tops about 50ish and cruise about 40 correct? What is cruise on the 525 boat, I've searched everywhere and can't seem to find a number.

I can not stand the smell of diesel boats and to tie up to someone that has a diesel generator running for several hours, not!
Leaves a nice oil ring around your boat.
As far as ideal cruise speed I have not really paid much attention. I usually run 40sh and around 3600 - 3700 rpm I think.
62MPH is a given and I think in ideal conditions maybe 64-65 top?

Ozark, how long have you had yours? Drive issues? Header issues? Thanks for the input. There are not a ton of 525 boats compared to the rest of what’s out there. I’ve not noticed the diesel issue when rafting off with the exception of the old boats?

My input may be invalid, if so please ignore.
Why not go diesel? They make more torque so your on plane and cruise would be quicker. How often do you plan on twisting up and running wot? If your more of a cruiser than top end runner I'd go with the fuel efficiency and torque of diesel. I've been around diesel boats my whole life. Only times I've seen oil sheen around them is if they have the ole wick turned up to the point that they think it's cool to blow smoke everywhere. I'm a little biased I suppose since I work on diesels. A properly tuned injection pump or in this case properly tuned ecm will produce just as much and actually more responsive power than the obnoxious clouds of smoke do. Just my .02.

I'm interested in a 370 and wouldn't want the diesels for the torque. Not that I don't agree that it's more important, it's just that a bravo drive and too much torque IS a problem. I found that out the hard way in a 382 with 700+ ft/lbs. While I'm looking for older than the OP I'd love to find one with 500's. However, I'm probably going to end up with 496's and a 4,000+ rpm cruise........just paying a little extra for gas every weekend.

I really don’t mind the diesel, but I do about 3-4 poker runs a year on lsc and it’s always fun to put the happy sticks to the dash!! In Michigan summers are short and sometimes it’s more about smiles per gallon. Again if I can’t find the right deal on a 525 boat I will look at the d370 boats. Also with all the technology out there with the diesels is anyone making a turner for those motors? Even if it was a mild bump to 425-450hp I’m sure that would get it moving?
