    Merc 3.0 Sterndrive Winterizing Question

    crack open a beer cause this will get to be worse than a oil thread... the cheaper RV marine water system ones are alcohol based and do not have corrosion in inhibitors in them. What marinas doing hundreds of boats will use is PG in a huge tub (100's of gallons) and check the strength pf the...

    Broken Skeg Tip...Repairable?

    Depends on what prop you are running. Price some of the higher end stainless and what you paid for the skeg repair is a lot cheaper. Last time i had my SS 4 blade fixed it was just under $300 so pick your poison

    Replacement of water circulation pump V6 4.3L

    Are you sure the noise is not from the belt or pulley? I also boat in fresh water and have never had to replace a circulating pump, on boats that have been 33, 25, and now 18 years old. You may want to see if the belt is making the noise or feel the pump for roughness by hand. Would hate to...

    Broken Skeg Tip...Repairable?

    I think it is mostly protecting the prop from a strike. I lost a bunch of each blade when my neighbor loaded my old boat on the trailer drive was still down... this was after previously giving the skeg a hair cut... had it been repaired skeg would have had some damage from the ramp but prop...

    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
