    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    I had the same problem with the bow stop because I had lowered the boat on the trailer by about 2-3”. So I would up lowering the winch stand to get the strap level and flipped the bow stop to get it to fit right. Much better now when I launched it this season it just rolled off like it should.

    4.3 Volvo Penta GL

    It may be flooding & getting too much gas if you smell it.This is a carb engine correct? Could be the needle valve, float setting etc…..

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    About the trailer For the bow stop you want the bow eye just under the upper roller, the way it is the bottom roller looks likely to catch on it & make it hard to get the boat on & off. That lower roller is adjustable and you can just raise it slightly. You main bunks look ok from what I can...

    4.3 liter 1989 Cobra problem

    With both ends disconnected there should not be more than 2.5 lbs drag in the transom shift cable. If there is slop in the remote control that can cause other problems like grinding into gear. The basic idea is that the shift cable must move with little resistance and you must get equal throw...

    4.3 liter 1989 Cobra problem

    It could be the adjustment of the shift cable, the bell crank in the pivot housing could be getting jammed up due to water getting in around the gasket, or the cable itself could be getting stiff. Anytime there is drag in the shift system it can cause the ESA system to be engaged too long & this...

    Bow U bolt Eye Tie Down Repair Question on a 20' Bowrider.

    Agreed not knowing how thick that area is, you want something to spread the load out, like maybe 1/8th" alu plate if you can get it cut to size, or galvanized steel plate. You can use wood but just make sure to really coat it in resin. PS I had to rebuild all the gas tank mounts for my boat...

    This happened today, and in the blistering heat.

    If you wind up replacing any rotted wood there I'd coat it with resin and seal the holes for the u bolt with Lifeseal or 4200 to prevent a recurrence.

    Thinking about upgrading to AGM batteries

    Might just want to check the charging voltage of your system, AGMs don't do well if they get overcharged.

    A good warning to all of us with old boats to CHECK THAT! especially with a roller trailer!

    Impeller Question with Rabbit Ears On

    160* stat on my 4.3, runs right at 160, might rise to 170 after coming off plane. Merc can have a 140 (older models) or a 160 (newer models), I'm guessing you have a 140, so that's about the temp you should run at. On your gauge, it should be on the hash mark between 100 and 175, that's probably...

    Thinking about upgrading to AGM batteries

    I added AGM batteries to our 2007 Grand Cherokee & 2017 Subaru with no issues….might consider them for the boat next time.

    Does anyone remember when car & boat engines only had.

    What I try to explain to people is this: Yes, modern computer controlled engines are more reliable than old school engines BUT: With modern computer controlled engines there are many more possible points of failure which can make troubleshooting & repairs more difficult when something does go...

    She just won't start easy nor stay running 4.3l

    Also if it’s back firing thru the carb you might have an intake valve that’s hanging open or not closing all the way. Any water in cyls after running?

    2002 Volvo 5.0 GXI Low Operating Temperature

    The other thing that's a common problem, is a grain of sand or rust flake caught in the 'stat, it keeps it from closing, it will never warm up till you run it on plane for a while. Sometimes that clears it out. I've also had luck with running it up on plane, bring it back to idle, and then tap...

    Does anyone remember when car & boat engines only had.

    Well yes, my first vehicles were air cooled 1200 cc VWs with simple points distributors 1 bbl Solex carb & 6 volt generator. The boat I still have isn’t much more advanced with a Prestolite points distributor 4 bbl Quadrajet; about equivalent to a late 60s Chevrolet. Just the way I like it. If I...

    86 Larson DC21 Engine Help Please...

    First thing if you’re keeping the OMC drive system which one do you have, Stringer or Cobra? Reason being is that the stringer drives used pre 1986 engines with 2 piece rear main seals, the Cobra drives all used one piece main seals. So with that the flywheels are different so you have to stick...

    Dead Batteries

    Wing nuts holding down battery terminals on the battery? If so replace with self locking nuts. I use marine grade battery clamps on mine. Easy to change when they get corroded. Also you can get green corrosion under the insulation that you might not see. I replaced all the cables in my boat when...
