    Force 50 driveshaft seal question

    I have a 1988 Force 50hp which I noticed the driveshaft seal upper (the one that goes into the motor on top of the driveshaft) was in 20 pieces when I changed my waterpump recently. Now my question is, how critical is this seal and what does it seal against since it appears I have been running...

    1988 Force 50 foot oil coming out when trying to fill

    Hello everyone, I was going to deal with this problem in the spring when I pull my boat out of storage but it's been bugging me and I can't let it rest. When I was winterizing the motor in the fall, I ran into a problem when attempting to pump fresh gear oil into the lower end. Gear oil was...

    Temperature gauge on Force 50?

    I have a 1988 Force 50 and I know it has an overheat buzzer but I was wondering if there is anywhere on these motors where I could screw in a temperature sending unit for an actual gauge instead? I don't trust buzzers, I would rather have a gauge I can keep an eye on to spot trouble early.

    Force 50 Fouled Plugs

    I have a few other posts concerning a seeming lack of speed from my Force 50 on my Capri 1500. I figured I would start a new post since I think I have a specific issue with my motor. I pulled the plugs on my motor Sunday and they were both covered in an oily, sooty film. I guess they were...

    Force 50 running on 1 cylinder?

    Hello everyone, in my never-ending quest to determine if my Force 50 is running correctly I have thought of another potential problem for my seeming lack of power. My motor starts fine, idles fine, accelerates to a top RPM of 4500; albeit slowly. I have to get the second person in the boat to...

    50hp Force Fuel Consumption

    I took a 29 mile trip on the weekend with my 1988 Bayliner Capri 1500. The boat has a 50hp Force on it. There were 2 adults onboard, 2x 6.6 gal tanks of gas, fishing rods, tackle box, cooler and miscellaneous small items. I cruised at 80% WOT most of the way (20 MPH) with the exception of...

    1988 Force 50hp Timing Adjustment - Help Please

    My 1988 Force 50hp outboard is currently spitting/coughing every 20 seconds or so at idle - a problem that I self-diagnosed through reading other posts as timing that appears to be slightly too advanced. My question is, since I don't have the tools to adjust the timing properly, can I simply...

    Lower ends and gear ratios

    I acquired a 1988 Bayliner Capri 1500 with a Force 50 motor in the spring of this year. The previous owner indicated she could pull a water skier no problem and could do 35-40 mph with the boat. She smoked a rock last fall and replaced the whole lower unit with one purchased from a used boat...

    Force 50 surges

    My Force 50 seems to be running a little funny. When it's idling, it will occasionally miss and almost stall but then return to idle. When i'm out on the lake I can run at WOT but occasionally it will speed up slightly by 1 - 2 MPH then settle back down. I recently had the carburator and fuel...

    Looking for prop - help please

    Hello everyone, I have a 15.5ft Bayliner Capri 1500 running a 1988 Force 50HP outboard. My prop is a Michigan Match 10-3/8 diameter, 13.5 degree pitch 3 blade prop. By myself in the boat, I can hit 26 MPH at 5600 RPM's and approx 24 MPH at 5500 RPM's if my girlfriend comes along. I have read...

    Tachometer acting funny

    I just installed a Faria tachometer on my 1988 Force 50HP outboard. When I turn the ignition key to on, the needle slowly starts climbing and when I start the engine it climbs past 7000RPM and stays pegged at it's maximum position. I specifically selected a 20 pole tachometer from Great Lakes...

    Tachometer and alternator poles

    Hello everyone, This is my first post and I apologize if this has been covered already. (I've searched for my topic but haven't found one exactly matching) I have a 1988 Force 50hp model D and a Teleflex tachometer. Looking at the application guide it seems to say 50hp (>1987 A,B models - am...
