Update: I found Universal parts dealers in my region devoid of parts, and Kubota not much better. Kumar did not answer their phone, and their website wouldn't take orders. Their part for the M-35 was $35 on their site. Amazon had the same for $105 + 48 for two day shipping. Part came, matched my dead one and last night I drove down to the boat and installed. I used a syringe to fill the pump chamber with Prestone water pump lube per Ron Hill, and filled the hot water heater hose, put my finger over it and guided it to the pump. Lost very little fluid. Topped of the chamber and started it up. Worked fine. No overheating, no issues.
Until, after running it for a second time at the dock at 165 degrees for 20 minutes. Pump fine. Buttoning up, doing the last search and saw my port side front engine bracket had sheared clean off where the gusset joins the flat. Might have happened any time prior as the engine was being held up by the remaining three brackets and mounts.
Searched this site, and saw a service bulletin for M25XP and M35C, from 5/1994. Well, I have a M-35. No A, B or C about it on the plate. Owners posted about their M-35A's from the same vintage as my boat. I took a shot in the dark and called Westerbeke customer service. Of course, Mr. Joe Joyce is not there anymore. I was put to Bob Massanti (phonetic) voice mail and have left a message. The lady in service, when asked what my call was about, said "your kidding." So we will see where this goes.
Toad lists what might be this part for about $800 each. C'mon, they can't be serious can they?
