Kudos to the Beta dealer, when I told him what I was removing he calmly asserted that that particular conversion from Diecon had never produced more than 60 HP, despite the 96 HP badge.

And he was absolutely on the money, according to the power output curve, if my tachometer is reading correctly, mine maxes out at 55 HP.

So Iíll drop 5 HP and 160 kg. Except, of course, the Nissan can only sustain 1400 rpm without overheating, so actually Iím currently capped at something closer to 35 HP, with quick bursts of 55 HP.

Looking forward to this conversion. I found myself listening to a Kubota excavator at some road works the other day and drooling slightly. The guy in the digger must have thought I was a bit odd, I rolled my window down to listen and the guy behind me had to toot his horn to get me to move.

Re: Repower costs... what am I missing?

Maybe you and moseriw got your wires crossed, here. When he asked about the motor, I think he meant the one you still have and want to replace with the Beta, not the new one.

Thatís so funny. I put a Beta 50 in my boat. While repower was in progress I discovered that the bobcat skid steer in our marina has the same V2203 Kubota engine and I loved listening to it once I found out.

Sometimes I open the cover just to hear the Beta purring along at 1850 pushing me at 7.2 knots...

Re: Repower costs... what am I missing?

I was not aware that the Beta conversion was the V2203 with a Twin Disc gearbox. That was the combination I chose when I decided on a DIY conversion for my last boat.

Since it was a one-off I decided to manufacture the bell housing from alloy plate rather than go through the pattern making process for a cast alloy housing and decided that whilst I was at it I would install two starter motors.

The SS fabricated, combination heat exchanger/exhaust manifold proved to heavy as there are only eight 8 mm bolts holding the manifold onto the head so I rebuilt just a water cooled manifold and installed four anodes in the block and used an expanding spigot through the alloy timing cover to carry the raw water into the block for a raw water cooled engine.

During the hull refit in Darwin I installed keel cooling tubes and the engine is now fresh water cooled with a small electric pump supplying cooling raw water to the exhaust system.

Gives the ego a bit of a boost when you see the professionals using similar ideas in their design.

Only one of a lot companies who claim to have all parts for any kubota.

Btw. Kubota, Cummins, Perkins, Catapillar, Ford, John Deere, Onan in the 70 and 80-ies are the best one can have.

Er.... ok. No argument from me. Except for the 70s and 80s bit.

Thereís a blast from the past. I remember when you first posted those conversion photos. I was impressed then, still impressed now.

If I still had a land base Iíd have been tempted to do the same. And there are even ISO gearbox adapter plates now which make the conversion easier.

Have you maybe considered that Beta Marine saw your post and decided to follow suit...?
