Volvo 63p

[WoundUpMarine]

Does anyone have any input on these engines? I am thinking about one of these for a possible repower. I was comparing them against the 370 cummins B series and cant see much of a difference. Both run around 2800 rpms and make around the same power. the volvo is heavier but it has liners, which is a plus to me, but im sure parts are gonna be more expensive. Anyone have any thoughts on the engine, good, bad ugly??

Thanks!!

Gearing

Great motors the key is to gear it correctly. If you can fit a 23 X 23 wheel go with a 2:0 gear.

What size wheel did you turn w/ the 320hp and 2.5 to 1 in your BHM? Getting ready to hook up the same hp and ratio and think I might swing more wheel than 26 square which is what I have on hand.

Thanks for some of the replys, it should be a pretty good fit in my boat, the same length within an inch and only about 3 inches wider than my current isuzu. It sure would be nice to be able to get up and cruise at 20kts when the weathers decent.

Hey John, Still running fine with allot more hrs on it !! I did just have to put a new alternator on it the other day though. Not bad after 11 years of abuse. I think the zapper finally killed it. We are going to fish this week then its coming out for a new top side.

petrel, i believe i had a 28 square and with the 2.5 to1 . there were and still are quite a few in my harbor in all different configurations. 20 knots with 370 hp is doubtful. i know billy had more power in the ruby and i dont think that did 20 knots but maybe im wrong. a buddy of mine had a cummins 8.3 diamond back when they first came out with a 2 to 1 gear and he did 17 or 18 knots if conditions were right, i think those motors were 400 or 440 hp. i found and I'm sure most of you know this....the boat carries weight alot better and is less affected by weight with a bigger wheel, this is why a 2.5 to 1 is a good choice with anything under 350 hp

There is one around here that swings a 28 square, but that's w/ 3 to 1 reduction. Another guy built one w/ 320 hp 3208 and 2.5 to 1 and started w/ a 26 square. He put on a net reel and several thousands of pounds of fish and the boat would still turn full rpms WOT. He ran charters on her in the summer w/ a 26/30 I think. I'm going to be running fairly light, so I was thinking 26x28 or 26X29.

Had a 63P 370hp in my Seaworthy 28. Pushed the boat easily at 20kts if I felt like burning the fuel to do it. Only issue I ever had was a pinhole in the raw water hose sprayed my alternator with a fine mist of seawater, so I replaced the alternator. Shit happens. Otherwise, nice engine for me.
