Ok I am new to this, in fact the boat in the picture is my first boat with a motor on it. Background; I got the boat basically for free I traded my 93 infiniti g20 with 222k miles on it that I had for two years and only paid $300 for it then, I traded outright title for title I know that parting the boat out would of made me 10x what I paid for the car but I needed a project, so here I am. I am doing a full cosmetic restore and know basically nothing about the out drives, I can disassemble a car and put it back together. But this I don't know if I want to attempt or not.

So I know I needed the upper gear unit and did some research and comparisons and found that from 270-280 where pretty much the same. So, I picked up a 270 upper for $180 on ebay and it is in perfect condition, no hesitation in shifting and no noise in the bearings and they are very clean. Now my questions begin with 1. how and what do I need to change the helmets over? 2. how do I get the front part of the upper gear housing that has my 2 bolt assembly off and on to the 270 upper with the 1 bolt? 3. how do I take out the female end of the u joint assembaly out of the transom? and last 4. is there anyone in the tampa bay area that will touch a volvo without it costing $5k to rebuild an upper? LOL

Thank you for any answers you can give me If you need any pics they are on my Facebook page here...

P.S. I have one more question, I had the out drive covered and the latest storm we had tore the cover off and rain water got into the out drive, how do you suggest I dry that up so there will be no water in my oil?

Welcome to iboats!

Sounds like you've got some work ahead of you.

1. Sorry I don't know how to convert to the two bolt helmet.
2. See #1
3. Don't quite understand, the ujoints should come out with the upper gear box.
4. Good VP tech who work on the older Volvos are hard to find.

Remember, that new upper will need to be shimmed to fit your existing intermediate assembly on the outdrive.

Good luck!

Unfortunatly all the things you need to do require some Volvo experience.When you change that stuff around they need to be shimmed.That is if the splines match
The two bolt helmet:4 allen head bolts,same with the 1 bolt.Easier to change the steering yoke,and change it to a 1 bolt..
This older stuff used a few different yokes with different splines.Some were like 8 splines and some were 15 splines.
Your pics didn't show so I don't know what you have apart.
I sent you a PM.Jerry
