    Boat struggles when Warm

    Well after all the fuel treatments, cleaning the carb and topping off with fresh fuel and a can of seafoam plus star tron for good measure, shes back up and running again. Went 6 or 7 miles with four adults and a full cooler and she did fine. Cranked right up to come back home. I guess she's...

    Boat struggles when Warm

    I used the stabil marine tune up that's supposed to help clean the fuel system. Fuel was stabilized at winterization.

    Boat struggles when Warm

    So it was clear. The gas was a bit more yellow than I'd expect but it smelled fine. Changed the filter anyway. Added stabil marine treatment and also ran quicksilver Power tune. The boat did want to hesitate a bit after all that was through and it was at operating temp but it seemed improved...

    Boat struggles when Warm

    I have a 2007 Tahoe Q4 with a Mercruiser 4.3 with TKS. The boat has always been very reliable and I have maintained it for the five years I've owned it. Out of winterization, the boat cranked up and ran fine this year on muffs. I'd taken it out a couple of times with no problems at all. Last...

    Mercruiser 4.3 Temp Alarm Question

    Oil pressure gauge seems fine. Boat has done this on the first trip of the year with fresh oil before so I don't think that's it. We also have a dedicated house battery so we don't leave it idling often.

    Mercruiser 4.3 Temp Alarm Question

    Got it. Thanks a bunch for the advice. I'll take a look when I get out on the boat again and report back.

    Mercruiser 4.3 Temp Alarm Question

    Correct, no noticeable impact on engine performance when the alarm sounds. I'll start with removing the lube bottle float sensor. If that doesn't fix it, where can I locate the tan/blue wire? Is that to the temp sensor? If yes, where is that located?

    Mercruiser 4.3 Temp Alarm Question

    Yes, I will try removing the pigtail from the lube bottle and see if it stops. If not, I'll try the temp sensor next. I'm not sure if it has TKS. I think the top of the carb air filter / arrestor says its Thunderbolt IV ignition. Edit - If TKS means no choke, etc, then yes?

    Mercruiser 4.3 Temp Alarm Question

    It's definitely full, I just changed the outdrive oil and topped off the reservoir a couple of days ago. I'll take a look at that though.

    Mercruiser 4.3 Temp Alarm Question

    I have a 2007 Tahoe Q4 with a carbed 4.3 Mercruiser. The boat runs great, fires up, will hit 50+ MPH at WOT, idles well, etc. The issue I have is that occassionally, under hard load, and usually after I've made a long trip, then idled, then it's back under heavy loan, the alarm will sound, which...

    Depth Sounder Issue on 2007 Tahoe Q4

    Hi All! I purchased a 2007 Tahoe Q4 last weekend. Boat is immaculate and everything works except the depth finder. It has a Humminbird round depth finder on the dash (no model number) and it seems to work fairly correctly when the boat is stopped, but it goes haywire when in motion. I was...
