My starboard side windshield hand knob had worn to the point the threads wouldn't hold enough to clamp the slide with sufficient force to keep the windshield open.  I'll add that the design is a bit…Continue

Hi John,

Interesting procedure that has eliminated the intermittent solenoid release before starting: When turning both start switches to 'ON', then turning the ignition key, both solenoids kick in forcefully, along with the buzzers, with each engine starting easily. I realize that the stb solenoid is weak and they are both due for replacement. I feel i can use the boat confidently until we do the job. Bill Mulvey, 73 Commander 41

Hi John, yes the whole vessel is a 32v , and no it did not come with the TCS system. So you’re on it and you know your Commanders well.Like most of us owners of these old girls, the 32v sourcing can be difficult at best. But anything that’s 32v , I pickup and try to repurpose or use it for inventory, thx.

Hi John, I was looking for a 32 v set up, I’m not sure I can use it. The vessel was third vessel made in 1966 previously owned by the Duponts and has been we’ll kept by her owners. She has twin Detroit’s and truly is a blue water vessel., thx.

 John, I would be interested in the 8 gauge cluster for my 1973 36.

Thanks! Craig

Hi John,

Thanks, It has been on the market for a long time.  I guess the pictures are not representative of the real thing.  Considering there have been many that have changed hands during the time that this one has been on the market.  I do notice that the mast is not predent in the pictures.

Did you look at the 1982 41' in Rhode Island before you bought your boat?

Hi John

I would suggest after commenting on your quest that this model and this commander I found on line (even though a broker has it) is looking good and has better head room and would be a better model for resale in the future. Plus I think that although it only has the master and the forward stateroom there also is pull out coach in the salon. If there is a 45 for sale near you go take the family for a look before you decide on a 47 to compare. I believe at your point in your reach it is worth a look and the 8v71N is a bullet proof engine. It is not as fast as some want but you don't have a turbo issue either.
