Volvo AQ125A needs rebuild

[jefe]

I have a Volvo AQ125A in need of major repairs, boat is in great shape, been garaged for most of its life Bayliner Capri/270 outdrive. I read on a forum a while ago that this engine is basicly a Volvo car engine. Is that true and can internal engine parts be subsituted? If so does anyone know what "car" engine it is. I was also told that there is only one other Volvo engine that will bolt on to the 270 outdrive does anyone know what engine that is?

Its a B21, B23 or B230 depending on year,(designation will be cast onto lower portion of block) and yes internal parts will fit.

Thank you for the information, this is what I found on the block:
9 then the "clock" 82 0622 above all that is a "D"

The boat is a 1982 hence the 82, would these numbers let the dealer know what engine it is? There is also the serial number plate, would that only refer to the marine engine application?

One last question, would an rebuilt automotive long block work?

Re: Volvo AQ125A needs rebuild

yes, B23 and B230 have a couple different pieces on it... the only problem is the AQ series have a different cam on there.. also the fuel pump is different for the B230 (i was told)

True.

Can you reuse your old head and camshaft?

Re: Volvo AQ125A needs rebuild

Yes, the head is fine as well as the cam, it needs a valve job and new pistons

What happened to the pistons?

Save your circ pump. The marine is different.

These engines are pretty tough. They usually out lasted the cars they were put in. What happened to this one?

The B# should be cast just forward of the distributor on the block.

A valve broke apart and pieces stuck in one (or more) of the top of the pistons. I'll look for the B# tomorrow, weather permitting

I was idleing at the time, the engine is a B21 and these numbers are stamped next to the B# 04995, what do these numbers mean?
