    Merc 4.3

    Even with an evened out firing order, a V6 has some serious Imbalances, I am surprised they don't shake the layers of Fiberglass in a hull apart.

    1400 RPM loss from 13 to 15 pitch!!!

    No it is not, unless one of them is incorrectly labeled. Okay, you have the 2.33:1 gear case, which, I believe, takes larger Diameter Hub props than the Standard case. Check you props, do they all have the same Diameter Hubs?

    Quit My Job . . .

    Of the 35 yrs I was with the Company, less than 12 were with good Managers. The rest were the stupidest Illegitimates you could ever meet. They were certainly Legends in their own minds. A couple of them took a Run at me, but within a Year, each time, I had managed to get them Fired. In one case...

    Spun Prop

    Back to the beginning What are the Compression Numbers? Does it have a Spark that can jump a 7/16" gap consistently, on both Cylinders? Is the Fuel System in good condition, no air or fuel leaks, Clean Filter/Screen, on motor and on pickup tube in the tank. Is the carb opening fully when the...

    Carburetor tuning on muffs

    Perhaps the screw was backed out so far, that it didn't make any real difference to the Mixture, or there was some gunk/gum/varnish in the passages that were restricting the flow and the needle wasn't making any change in the range you turned it. Another possibility is that the Middle carb...

    Quit My Job . . .

    Management, pretty much the Least Productive bunch of People in a Company. My Motto, which I did write on many White Boards, with regular Felt Pen(much harder to remove in a Hurry) "Keep Smiling, the Bosses are IDIOTS!" Respect is earned, 99% of Management deserves None

    1400 RPM loss from 13 to 15 pitch!!!

    Are those Dia and Pitch numbers on the Prop, or just from the Box? There is possibility that the Prop is mislabeled, as well

    Help IDing Trailer

    That trailer looks very much like the one my dad had under a 1980 Mirrocraft but a lot shorter, but different colour. We bought the Trailer at a Canadian Tire Store, as to who made it, who knows. I would guess that the Axle is not the one that came with it, it looks heavier, and the Tires are...

    Never owned a boat!

    Well, your mind is made up, and you are hoping someone will give you the Answer you want to hear that confirms your line of thought. You can tow whatever you want, with whatever you want. But if there is an Incident, and the Insurance company(s) does its Diligence, and they will, you might find...

    What is this on the transom?

    There is a risk of building a hull Too Rigid, and having the Glass shear along the beefed up Stringer/Keel. Perhaps if they put down more glass on the Hull, and not just the Stringers/Keel...

    Engine clunk on first start

    Hydrolock means unable to complete the compression stroke, so how would it start and run?

    What is this on the transom?

    If people were see how the boats look prior to the floors, the trim pieces the cover the seam between Hull and Cap are installed, and the carpet being glued down, a lot of boats wouldn't be bought.

    Cavitation Burns

    In 2002, I found a submerged Rock Ridge, with my Stainless. Neat thing about Stainless, the blades will tear, bend, but not break off, eventually you end up with a bent propshaft, and a sculpture Aluminium is more forgiving
