Re power with new sail drive

A few boats have repowered but haven’t shared a lot of details. If I had to repower I would consider the Yanmar 1GM10 with the SD25 saildrive, but it wouldn’t be a drop in solution.

Are you having engine or saildrive issues with the Bukh?

Replacement pumps are available (Johnson F35B) or you can rebuild your existing pump.

The pump is easily replacable and there is an upgrade pump - search it on the forum  . Yes it will leak  water into the engine .  The new pump has a roller brering instead of a sleve so the seals last longer as the old one would wear oval .You will either need to grind your existing hold down /bracket or order the new ones (grinding is easy ) .  That Bukh is hard to beat , mechanical fuel pump so she will run with dead batteries and you easily can pull start it . It is stone axe simple . Nothing else is as light or will fit in the same space . Burns just a liter an hour  - efficient . My only complaint is the lackluster charging . 

OMG! Do not change out that beautiful Bukh, nor its sail drive for anything else because of a leaky water pump. They are both wonderful pieces of machinery and are easy to fix. There are plenty of parts available to do whatever you need. Any change will wreck to boat in my opinion, other than to retain the sail drive and switch out to an electric motor with battery power. Here in BC, two Laser's have done that within a budget of CAD$6,000.

Hi Gerry - probably a little late to the game, but the water pump is a dead simple replacement --- even I managed it!!!!

Hello Geoff,
The Bukh spare parts listing (assembly diagrams) shows that part as 610G0100.
