Hi Burt, Moyer Marine has a service and repair manual they sell for about $50. It's worth it. I'd also recommend a fresh water cooling kit to stop any more salt water running through your engine. You can run a hotter thermostat to run the engine at a better temp. Moyer sells a kit that adapts a pulley wheel to the front of the engine to run a mechanical pump and Indigo marine sells a kit with electric pumps if you don't have the room on the front of the engine for the pulley. I installed the idigo kit with 2 electric pumps. I plumbed it so if the running pump failed all I'd have to do is redirect flow with a diverter valve and install a fuse to run on the spare pump. It was Tom Steven's idea from Indigo. I don't have an answer for you on the zincs though. Moyer forums are great resource as well. As far as backing down or running in reverse, If you have the 1:1 ratio in forward and 2:1 ratio in reverse set up, you rev the heck out of it in reverse to get the same spin as in forward. My boat had a Michigan Wheel Blue Dot 2-blade folding prop and it went like a banshee in reverse but, I ran really high in the RPMs to do so. It was even common practice to spin it up in reverse to open the prop and then pop into forward. It worked well but it but a lot of stress on the drive train. I ended up putting a the 3-blade prop on from indigo. It gave me better RPMs in forward and I still had the rev the heck out of in reverse. Nice prop and more kind to the drive train. It did add some drag though but I don't race so I didn't care. Still saw speeds in the 7s Hope some of this is helpful... Danny,Still shopping in Massachusetts

So far it has been a very pleasant experience. I am reasonably sure it is original to the boat. It has a couple upgrades like electric fuel pump and electronic ignition (no points). Ran great through a short season last year. No issues of any kind. Just needed to figure out how to stop the boat and back her down with a two blade folding prop…. lots of patience. I do need to find and replace all the zincs, though. It is a raw water cooled motor and no water heater in the cooling loop. Is there a document available that will identify where I might find zincs on this motor? Maybe an owners manual or service manual on line? I have an owners manual on the boat but it is pretty beat up. Burt 1974 C&C 33-3 quarter tonner On the hard in the back yard Walpole, MA
