[Jay Curtis]

is there anyplace i can download a manual for an AQ275 i am about to remove one from an 86 bayliner to see if i can save the transom

bayliner is missing the motor it was a 305 chevy

i just picked up a 1966 marktwain that some one has installed a newer volvo AQ275 with a a 260 B motor i assume that this is a 350 chevy

not sure yet of the condition of the motor or of eaither one of the out drives is there anything i should be looking for on thedrives

yes, you can put the 260 where the 230 was.

if you want a bit more power, you can even upgrade the cam or install vortec heads.

you can download manuals from http://www.volvopenta.com/volvopent...lication_search/Pages/publication_search.aspx

you can view the manuals on-line at http://boatinfo.no/lib/library.html

The 260 is the 350Chev.
Check the oil? 30wt not gear oil.
Pull the drive and check the universals?

You are not going to find a manual for your AQ275. Your AQ275 should match a SP/DP-A. Volvo Penta can be mix and matched between several different models so can be hard to identify with certainty. Post a pic from the side as that will help identify what transmission you have for sure.
Also the proper gear ratio you are looking for is 1.61:1
Take off the anode behind the prop and clean it off. Stamped someplace on the carrier will be the gear ratio of that lower unit.
Here is a Downloadable Outdrive manual.

The 275 is not like a DP-A. The DP-A is what the 290 became

Manual with 275 is in both of the links I listed
