Well - It seems my 32 year old old Volvo MD17 has come to the end of her run time.
Over the last few months she's been running a bit hot if I pushed it over 2200 rpm. Then a week ago, I noticed signs of water in the oil. I changed the oil, and tried to re-start the old girl. No luck. I bled the lines, changed the filters, but no fuel getting up to the injectors; it appears a faulty injection pump is the culprit.
Hmmmm... Injector pump + head gaskets? + liners? + ????? = $$$$$$$$; and I would still have a 32 year old raw water cooled engine.
I stopped here. Rather than rebuilding the injection pump, then chasing the source of water in the oil; I decided to cut my losses and re-power. Getting parts for these old Volvo's is becoming more difficult and expensive all the time. I could get part way through a rebuild and find the required part is no longer available.
So - I'm waiting on a few replies, but I'm leaning towards a 43hp Beta (Kubota). They are non turbo, fairly low (2800) rpm, and have the engine layout that matches my limited access.
It gives me a few extra hp to play with, to drive a bigger or 2nd alternator, and possibly a future refrigeration pump.
Another Sydney company, WM Diesel also marinizes the Kubota.
I'm still working out what gearbox setup to go for. My current Volvo MS2 has a 7 degree downward offset. I'm checking to see if I can get a similar gearbox which can be driven either way allowing me to re-use my existing newish LH prop.
Oh - the joys of boat ownership.
