A GOOD MARINE MECHANIC TO REBUILD 2 X VOLVO PENTA AQ170 ENGINES

Still amazes why people buy these "project" boats and then ask for advice on fixing them. Why not get that advice first ?

There is a mobo berthed close to me that the owner paid £65K for, if it was really nice it's worth, maybe, £70K. I was asked to look at it with a view to putting things right, it needs so much work doing that i couldn't even hazard a guess at the cost. One engine suspect, Genset U/S, wiring shot to pieces, every single electronic system shot, all instrumentation on the flybridge UV degraded, upholstery needs replacing, vinyl linings knackered, gelcoat in need of serious work, including previous damage repaired with what looks like P38 etc etc etc.
 
Fred Drift.
Seem to recall from posts on here many moons ago that the timing, cam shaft angles and even the lobes were all different on the marine petrol engine from the road versions.
Assume that the power/torque needs to be a lot lower down the rev band.

4 pages back the OP did not ask for advice how to fix........................... BUT advice on who could fix!!

On the assumption the OP has all the money in the world and is totally in love with his project......... he does not need to know how to fixit..................... just issue the command fixit!!

Correct

A bit of Fred drift, could you not take out the two engines , then mount two out boards through holes in the bottom via tunnels above water line . This way you would not have to strengthen the stern.

Interesting bit of lateral thinking. You would need to mount the outboards to something though. New internal bulkhead?

If it had outdrives on the stern, shouldn't be too much strengthening ?

If it was only intended to use for inland waterways a single outboard might be enough.
 
Bouba: How about make the engine room into an extra bedroom and put one or two outboards on the back?

Interesting idea but how would you tilt outboards?

It's been done a lot over there, both as original and retrofit when repowering.

The buzzwords to Google is "outboard bracket".

Remove the old engine(s) and fit a bracket for the number of engines you want:

Thank you
Yes aware of Gill Brackets and similar but Seastoke is referring to fitting outboards into through-hull tubes.

more holes to sort out and the outboards are then inboard with the associated lack of access to the motors etc

O/B on the stern a great
