Volvo Penta VP700 -78 renovation.

[Per]

Hi
Just wanted to share some pics from my latest project.
Take a look here:

This engine had two siezed pistons and was missing a carb, other than that it was in very good shape.
I desided to do a heavy cleanup of the ports while it was apart.
The wheather is still a bit to cold to permit a test start but ive prepared a test stand so that it can be run on the hose whitout lower unit.
Time will tell if it works or not!
The last one I did turned out very good but were more bottom end grunt than top end performance, this motor was given some more exhaust duration (and wider ports)
As well as more free flowing intake (duration and area).

Production of these engines stopped -79 when Volvo dropped the outboards.
Part are still quite easy to find except for pinion gears and oversized pistons, I think I bought the last decent second hand one in sweden
Hope it won't sieze again

Thanks for looking

Thanks Per. I like 3 cylinder outboards and I like rotary valve 2 strokes

Added a short video in the Picasa link in the first post.
The last pic is not at pic but a video...

I was very pleased with how easy the engine started, it idled pretty much perfect but of course it remains to be seen if it works on the boat.
Fuel is alkylate based 95 RON with 4% oil.

Its LOUD without the LU

Finally things are moving in the right direction, this is a short movie from my first tests of the boat with the engine that started this thread.

Just cruising have a very young passenger...

Great photos! (Often wondered how they got a rotary valve to work on a three cylinder.) Interesting to see that, like the old Merc triples, it has two carbs for three cylinders.
