No engine manufacturer makes their own starters, alternators, fuel lift pumps etc. etc.. They are all pretty much the same. Yanmar uses Hitachi alts & starters, Westerbeke uses Mitsubishi, Balmar or Leece-Neville. I have not found a single brand to have any more or less reliable alternators, starters, fuel lift pumps etc.. They also use pump companies like Johnson, Jabsco etc. to make the OEM pumps. Some Yanmar's share the same pump parts with some Westerbeke engines because the pumps are built by the same OEM supplier...

There is not an engine maker I know of that makes a decent wiring harness, just a sad reality.. Yanmar IMHO, as a marine electrician, is one of the worst when it comes to wiring harnesses.

They all pretty much use crappy on-engine wiring.

Westerbeke engines are marinized Mitsubishi industrial engines not Kubota's. Universal, Westerbeke's sister company, marinizes Kubota's.

Kubota parts are a LOT, LOT, LOT less expensive than through Westerbeke. I have saved over 80% on many Kubota items. IIRC I have paid about $7.00 for a Kubota glow plug and Universal wanted about $80.00.....

Even Mitsubishi parts are a LOT, LOT, LOT less than through Westerbeke but finding the Mitsubishi parts can be tedious as their "contract" with Westerbeke disallows for Mitsubishi dealers to sell parts to Westerbeke customers, if they know they are going on a Westerbekje engine..

I work on all the engines and I don't find Westerbeke / Universal to be out of line parts price wise for the "marine" market.. Volvo is the worst but they all GOUGE for the "marine" label.

BTW if you get creative Yanmar parts can also be purchased through industrial/farm channels too. These engines are also widely used in industrial and farm applications. There are a LOT of John Deer / Yanmar powered tractors out there and even through a John Deer dealer (not known for inexpensive parts) the base engine parts can be had for quite a bit less...
