Hi all, first off an introduction, I've just joined the forums after buying my first boat last week. I'll start off by saying a big thanks to the community for all the knowledge I've already gained from reading so far, it's been invaluable! My dad has owned boats all my life so I'm no stranger to them, plus I've always worked on my own motorbikes/cars so I know a bit about engines, but I have to say with some things on the boat I wouldn't have had a clue about without this/similar forums.
So last week after looking for nearly 5 months I finally found a boat in my price range and with the spec that I wanted, a 1993 bayliner classic 1600 with a 1995 force 120 outboard. Now I know these are renowned for being a fairly "cheap" pairing, and many people on this forum and others have a strong dislike for the force engines, but after a lot of reading I came to the decision that this was such a simple engine that even if things do go wrong I should be able to do 95% of the labour myself (leaving room for bits that need special tools). Plus the previous owner had all the receipts for a full service only 6 months ago, and it was the only boat I really fell for that was in my price range, so the decision was made, mock me if you will
I plan to look after her well, I've already fitted a voltmeter to track charging, and I've got a temp sensor/guage and a tachometer on the way to try to keep on top of the engines health as best I can.
Anyway, I managed to get the boat in the water for the first time yesterday (at a local tidal river/estuary), and launched/started etc all fine. On its first application of power though I noticed quite a bit of play in the engine (i.e. prop moved toward transom under positive throttle). Once underway, the movement in the engine was very little and the steering quite stable, but I throttled down again and did some investigation, and it appeared to move quite a bit when knocked into reverse as well. I also noticed that when rapidly reducing power the boat would turn slightly. With the boat back on dry land I wobbled the engine by hand and could feel a lot of play. After doing some reading I found that it is likely the upper & lower engine mounts that have perished and need replacing.
Looking on this site and similar ones for parts I cannot seem to find the upper mounts anywhere on the parts diagrams. I've found the lower mounts (under the driveshaft housing diagram/section), but not the uppers. EDIT - typical, I've now immediately found them listed under the exhaust plate section!
So, long story short (apologies if I went on too long :laugh, my question is has anyone ever replaced the mounts on a 95 force 120 that could shine some light on what needs to be done? I know the block needs to be removed to get to the upper mounts on quite a lot of engines and I am prepared to do that if necessary (I'd rather not of course, but it would give me a chance to check the crank/seals/pistons etc). EDIT - Now that I've found the engine mounts on the parts diagram I'm now pretty sure I'll have to remove the block, but again if anyone's done this before I would very much appreciate any advice.
Many thanks in advance to all you lovely knowledgeable people
