Walter V Drive Winterizing Question
My question is:
1) do I need to do anything else with the Walter V-drives to make sure that they're good for the winter?
and
2) given that Walter recommends pulling the top cap and inspecting seasonally, would it make more sense to do it now, and dump some antifreeze in the coolant passage, and leave it loose for the offseason?
It is my understanding that Walter recommends a new gasket at the top of the V-drive, but would a premium RTV work as well? Doesn't seem like it gets much pressure.

Re: Walter V Drive Winterizing Question
Personally I prefer using proper gaskets when possible. If you're going to use a caulk, make sure none oozes out on the inside. It won't present a problem for the Walter but it will end up in your oil cooler on the engine if that's the way your application's cooling circuit is run; from hull to the Walter then on to the engine. Not all are routed that way.

Thanks Viper, another site had it posted that there's some "honeycomb" weave that, if you have a saltwater boat, you should coat in epoxy. I wanted to make sure that same honeycomb pattern couldn't collect water and freeze crack. I couldn't get the supply tubes off, but I'll pump some antifreeze up through the exit port.
Doesn't seem like there's a reputable distributor that makes a top plate gasket for a reasonable price. Looks like I'll be making one out of a flat sheet of gasket material, or using permatex.

Don't know where in Michigan you are but try contacting Anthony Keats Marine north of the boarder not far from Detroit. Heck, with the American dollar exchange, a gasket should cost you 5 cents

Thanks for the contact. My model is the RV-40. The gaskets that I found were around $35 online. That's ridiculous for a flat, cork gasket that I can make in 20-30 min. with a razor knife and a hole punch. I'll try your guy.
