Best Transmissions

I am re powering a Coronado 35 and thinking of buying a M35B Westerbeake diesel without a transmission. The normal transmission to buy for this is a Hurth ZF10. Is this the best transmission for this? Any other suggestions. Also any comments on the Westerbeake M35B?

Re: Best Transmissions

Take a look at the PRM120. I installed one on a W38B4, which I think is a larger version of yours but the housings are the same. Call Westerbeke and they will spec out the bell housing for you.

Re: Best Transmissions

Twin disk trannys fit the same bolt hole and dimensions as a hurth, but are far better trannys. I am not to impressed with Hurth trannys having had several destroy themselves in short order, as have some of my clients. Going one size bigger, up to a 150 gives a huge improvement in capacity.

Re: Best Transmissions

I had no problems with an oversized Hurth, but there are plenty of horror stories about pleople who relied on their sizing and burned up multiple transmissions. When they sold me a Beta they said they had switched to Twin Discs because of the Hurth issues.
