Re: What can I do to my AQ131A ?
the good news is that the 275 drive is a good design, and can handle 200+hp, and parts are still available<br />I believe there is some interchangeability with other volvo drives.. like the 280 or 270.. even the 250 and 200, but not the 80, 100 or 100B<br /><br />The bad news is :<br />1. your bellhousing. It is Volvo 4 banger specific. Volvo did put an inline six (3 liter I think?) in boats which may have the same bellhsg. But I seem to recall parts avail. is poor specifically exh. manifold.. people were quoted $2000<br /><br />2. your outdrive ratio. It is geared to rev the engine high, and turn the prop slow. perfect for a heavy slow boat with a small engine. If you add more power by any means, you must at least increase prop pitch or the engine will over-rev, if you're already at a 19P or 21P prop, then you are pretty much in need of a different Volvo drive as you add power.<br /><br />Best solutions:<br />a) look for a donor volvo powered boat with a bad hull... Volvo used 3.8 and 4.3 chevy V6 engines which would be nice in your 19'<br />b) sell boat and buy another boat
