I have the opportunity to purchase a marinised Kubota D722-E 18Hp motor with a genuine 131 hours on it quite cheaply. It has come off a Seawasp generator, the generator died prematurely and the motor has been sitting in a shed unused for quite a while (photo below). Do you think it would be worthwhile considering it as a replacement motor for my Carter 33?It currently has a Yanmar 3GM30 27hp that runs quite well but you never know with old motors. Looking at the calculations online, a boat like mine with a guesstimated waterline of 28 ft and and a displacement of 4.5t it should ideally have a 20 hp, so the Kubota is slightly undersized and the Yanmar a bit generous. Also what are the logistics of modifying mounts and matching with a new transmission?

Any recommendations greatly appreciated.

If your current engine is working I wouldn't go to the effort to install a used engine, labour will be high + you need gearbox and panel etc

and possible alignment problems with a different motor gear box combo.
How many turns on the starter does your old motor take before it starts?
is your a sail drive or a gearbox on the back of the Yamnar

Thanks for your advice everyone, I agree it is not worth the effort when I already have a good motor that is easy to start uses little oil and now that I have moved the giant compressor from the engine bay can work on the the port side of the engine and fuel tank with ease. I don't really want another machine to store so I won't bother with it. If anyone else is interested in it I can help with facilitating the sale.
