    Stingray mercruiser 3.0 engine problem

    In additon to the info chris wanted some more on what happened? Just stopped running? Does it turn over via the starter and not run or dies it not turn over at all?

    out drive

    That's the transom housing serial number the outdrive serial is located by the vent plug on the upper housing- just below it. It will be not only in the sticker but also stamped in the metal is the sticker is gone or damaged.

    1990 5.7. 260 Overcooling at idle.

    Couple of thoughts- is engine actually getting that cold? Have you measured the water cross over in intake at idle to see if it matches indicated temp? if indicted temp is not accurate is the temp sending unit in correct spot in thermostat housing? Is it somehow just seeing the raw water...

    Power Trim Up not working

    That circut breaker is the 12 v supply to boat I think trim gets it direct off the battery cable to starter so resettting it will have no effect. It is working in the up so as previously mentioned likely the trim limit switch is bad. often time folks will jumper around it as it is a pain to...

    Lake boat sizes: Is there a trailerable sweet spot?

    GPH depends on how much you push the throttle forward. We are lucky enough that my dad has a place on the lake, so I'm only trailering twice a year, kept in a hoist. Typical day is 6-8 people out for an hour or three, ski/wakeboard, then swim. Put about 35-45 hours on it a year = about...

    Bellow Replacement

    Did you get the tool to remove the hinge pins? Also I think you need the shift cable tool as well to remove shift cable from bellhousing. Might be worth doing the shift cable if yours it not smooth and also the seals on the shift shaft in bellhousing can leak water into bellhousing if they are worn

    Lake boat sizes: Is there a trailerable sweet spot?

    Really depends on your tow vehicle and comfort towing. I can tell you from my experience on a 38 mile long lake with my old boat (18 ft 1991 sea ray 170) vs my new (21 ft 2004 sea ray 200 sport). the extra beam weight, and deadrise may it a much more comfortable boat that is towable by my...

    4.3 over heating at low rpm Help

    Did you verify the engine temp with a IR thermometer to see if the alarm switch is accurate and should be going off ? checked the ignition timing isn't retarded? Did you test it after the circ pump was replaced?

    Prop for new Quicksilver 3.0 Marine engine with SEI sterndrive

    Do you have a history with this boat ? Do you know what previous prop pitch and wot rpm was ? If not id say start with a 19” pitch black max see how it performs. If you focus on watersports may want to consider lower pitch or 4 blade, but 19” would likely be a good all-around pitch

    Mercruiser 3.0 ignition module

    neutral is fine, just dont run it very long at that rpm if on muffs/hose Helpful to know what you actually did vs what you posted in first post. If u are sure you are applying 12 v to set it in base mode module can be the only issue. If it is still advancing ok set total advance and if it works...

    Another 140 Delco EST conversion thread

    29 degrees total minus the 6 degrees initial means the distributor advance is 23 degrees when all in . at specified rpm level- it doesn’t come in all at once

    Bellows inspection check what do You think

    Mercruiser 3.0 = Chevy 181 CID = Small Block Chevy Valve Train? 1:65 Rockers?

    https://marinepowerusa.com/wp-content/uploads/2019/08/30lspecs.pdf last page has dyno sheet from GM Read what Chris wrote about gear ratio and props. boat is different than a car because there is no transmission... so if gearing and prop pitch isnt low enough engine will never get into the...

    Ford 302 spark plugs

    I dont think that would hurt at this point maybe a valve stuck down or dropped. I would just keep the supplier in the loop to and take pictures or video yourself doing it. When I did my repower I took a video of priming the engine and test running with oil pressure and temp gauges hooked up...
