    Stumbling at Cruising Speed - OMC 5.8L

    Been working on my 1989 Bayliner Trophy 24' and it ran great... for the most part... last season, but I need help figuring out an issue. It starts fine, runs fine, but after about 5 minutes at cruising speed (1/2 to 3/4 throttle) it starts stumbling. If I throttle down and then bring it back...

    1989 Bayliner Trophy Fresh Water Tank Questions

    It is a hand pump located on the sink right now. Would like to change it to an electric pump in the future to help drain it out in winter. Not sure I can get to the drain plug in the tank and the hand pump would take a really long time to drain it down.

    Throttle Control Button, need a replacement

    That's a bummer.... Your saying I need to replace the entire control? Not sure I want to do that. It still works as is. Maybe I can fabricate something.

    Throttle Control Button, need a replacement

    I have a 1989 Bayliner Trophy and the center neutral button on the Throttle control is missing (was missing when I got it). Any idea where I could get a replacement? Can't find one online anywhere. Engine is 5.8L Omc Here is a picture of what I'm looking for:

    Can you get to it? Mine seems out of reach under the fiberglass floor

    1989 Bayliner Trophy Fresh Water Tank Questions

    It's a recent post.. this fall. I just dumped a ton of antifreeze in the tank for now. Where is the drain? How do you get down to it? I don't know that I can get access to the tank.

    Anyone had to drain the freshwater tank before?

    1989 Bayliner Trophy Fresh Water Tank Questions

    Is there a way to drain down the fresh water tank for the winter on these? I think its 13 gallons. If not I think I am going to add a 12v water pump for the sink and to help drain it. Anyone know what size the existing water lines are?

    What size trailer winch?

    Good to know. Just wasn't sure if that lb rating was for actual pull rating or just was size boat is meant for.

    What size trailer winch?

    Thank you. So a 3000lb winch should be sufficient to pull a 4000lb boat into a trailer?

    What size trailer winch?

    Right... that's what I'm concerned with. How strong is that connection?

    What size trailer winch?

    I have a 1989 Bayliner Trophy 2459 that weights about 4000lbs. My cable trailer winch just snapped and looking at replacements they only go up to 3000lbs. Is that sufficient to pull it up on the trailer? Is not lifting it vertically... so not sure how these are rated. Also how strong is the...

    1989 OMC 5.8L Stern Drive, Rough Starts

    Idle screws were set to the same setting they were at prior to the rebuild, have not been checked while running the engine, Ill check that out and see if I can get a better idle, but it idles fine once warm. The ESA seems to function in that the motor "stumbles" when going into reverse. Is...

    1989 OMC 5.8L Stern Drive, Rough Starts

    I am not sure if it has points ignition... So that has not been checked. Ill read into that process. I don't believe the ESA is the issue with starting, just shifting, correct? Choke appears fine, only by visible checking its position while cold and warm. Not sure about the idle fuel mixture...

    1989 OMC 5.8L Stern Drive, Rough Starts

    Just fixed my shifting issue and now I noticed that the engine seems to crank a bit too long before starting and dies going into gear at first, before warmed up for a bit. I would like to troubleshoot this, what should I be checking? My guess is a distributor/ignition issue as I checked all gas...

    1989 Trophy, Adding 2nd Battery

    So I tapped the deep cycle battery into the red/purple line near the starter solenoid and disconnected it from the exiting path and it seems to have worked and doing what I want. I just need to do some more verification to make sure there are no other crossovers from one battery to the other...

    1989 Trophy, Adding 2nd Battery

    Understood, it will be on a maintainer when not in use, just would like to have the alternator charging as well while in use.

    1989 Trophy, Adding 2nd Battery

    Ah, I see what you're saying. Even if I disconnect the red/purple 12v supply at the engine, there is the scenario where the bilge switch is on and the float valve is activated that it would backfeed from one battery to the other and be way to much amperage for that wire... probably just...

    1989 Trophy, Adding 2nd Battery

    Yeah I see those connections, but I want to interrupt the 12v supply from the red main line from the engine to the fuse box. I think those ones run separately on their own.

    1989 Trophy, Adding 2nd Battery

    Just like to have both charge off the alternator. The load of the equipment is low (10 gauge, from the diagram I see) but the battery to battery connecting is high load, made sense to keep the batteries close together to minimize that length of high amp cable. Also they will both charge with...
