Hey y'all! My name is Jena. My boyfriend David and I purchased a 1987 Mariner 3297 that needed some TLC. We've replaced one of the engines already, and it's twin is going in this week. We have a question about the steering cylinder, as neither the cylinder nor any of the owner's/parts manuals came with the boat. Is there anyone who may have the time to answer a few questions? We're located in Kemah, TX, and we love it here on our new-to-us boat!

Re: 1987 Mariner 3297 owner with lots of questions
The steering should be hynautic steering. The pump is at the steering wheel and on port aft wall there should be a stainless steel canister that has the hydraulic fluid in it and has a air valve that you pressurize with about 30 psi.

I probably have some of the diagrams and instructions. Mine is an 83 3607, but I'd be the parts are the same.
What questions do you have?
