Transmission rebuild/repair

[garybodie]

I have a A27 sport model with the Westerbeke 100, and need transmission repair or rebuilld. Transmision works in forward, but no reverse. I've checked fluids and connections. I'm not planning to do any of the work myself, but I want to be somewhat knowledgeable in discussions with the shop. How hard is it to remove the transmission? Would the engine need to be removed as well? I'm leaning towards having the marina remove the transmission, and then carrying it to transmision shop for repair. Any recommendations in the southern Chesapeake Bay area? What am I missing? Guesstimates on costs or labor hours?
Thanks in advance

We had same boat with the W100. I had the transmission rebuilt and it was not too difficult to remove. The nice part of that setup is that the engine sits on 4 mounts so there are no mounts on the trans, meaning that you do not need to remove the engine or support it. The shaft needs to pushed aft as far as it will go (to the rudder) to make clearance. Remove the shift cable and unbolt the trans and lift it out.. I believe that one bolt required me to grind down a wrench due to limited clearance. You may need to also remove the exhaust hose between the elbow and muffler. I think I did it myself (not a pro) in a couple hours. I'd also take a look at the clutch/damper to as this is a good time to replace.

I don't remember the cost as it was few years ago. Good luck!

I have a 27FC with the MIghty Lehman and a Hurth transmission. Four years ago I had exactly the opposite problem, could go backwards but not forwards. After removal of the tranny by the marina mechanics I took it to Maryland Transmissions in Churchton MD (near Herrington North), who stripped the tranny and rebuilt it and put in a new damper plate (updated from the original 1984 model). Marina mechanics then reinstalled, and I haven't had a problem since then.
If i can find the invoice I will post it but I seem to remember the whole thing cost about $600.00 start to finish. This was at the beginning of the season, and they had the tranny for about 7 days
