    Tb IV intermittent spark ?$#???

    Safety is for sissies.. electronic components either work or they don’t. If its guaranteed to be functional its no issue. so many of the TB modules are NLA so not much choice.

    Tb IV intermittent spark ?$#???

    I am running a used one for the last 8 years on my boat, and bought a used spare. If they list it as working you can try it out when you get it. Either way for $400 for a new one that less work and cost than a delco est You should check the wires for corrosion and resistance since the boat was...

    Broken Skeg Tip...Repairable?

    The only reason to repair it is if the prop is larger in diameter than the now shorter skeg... If you bottom out on some thing hard it will lift the back of the boat up and not damage the prop. Had this happen to me as our dock is in a very shallow cove. Idling out in gear outdrive most of way...

    Overheating

    No the thermostat would have no bearing on the impeller. Even with thermostat closed the cooling system is constantly flowing cold water to the exhaust system otherwise your manifolds, elbows, and rubber components in the drive and exhaust would melt. So the impeller always has a path to...

    Mystery Knock -- Insurance and Warrantee

    So you do not have an engine oil temp gauge just the filter felt hot? Which seems normal. If you had a mechanical issue in engine like you mention it would not be intermittent. let the mechanic pull the drive check gimbal bearing, see if any metal or water is in gear oil take the cap off and...

    Mercruiser 5.7 MCM carb low idling

    My raw water cooled engine with a 160 stat runs 170-175 also I don't think this is a contributing factor. Does the TKS module shut off enrichment if this is enriching the mixture at warm idle this could cause it to stall. Is the throttle pushed fully back against the idle speed screw thinking...

    A decent prop repair shop can weld that back up no issue. it is a minor damage certainly fairly normal in the course of a boats life, certainly not a reason to not by the boat

    OMC to Merc swap in 1996 Sundowner 195

    Yes correct the one pin is unused. I believe they should work. You are smart to get a complete drop in vs piecing it together How is the structure of this boat in terms of transom and stringers?

    Stalling when warm

    As mentioned see if float bowl is overflowing or dribbling fuel down after shutoff. Open the throttle is how how clear a flooded engine to start it. would also check fuel pressure if fuel is overflowing the bowl. too high fuel pressure damaged dirty or non functional needle and seat float...

    1976 Columbia 16.

    As mentioned look through the restoration section. Unfortunately what you see is likely the tip of the iceberg. The wood in the stringers and the transom are a significant portion of the structural integrity of the boat. I would drill some holes in several places in the stringers and transom...
