    1150 Link & Sync Question

    Here is a bit of info from Mercury regarding engine height Power Trim: Trim in/down fully to get on Plane, raising the engine as boat gets on plane. As speed increases, trim out until boat starts to Porpuss<sp>, then trim in a bit till it stops, or until the Engine trims out as high as the...

    Tin Rig Tow Vehicle

    I wasn't aware of Pontiac offing a Tow Package Option, of course I will admit to not knowing much about any Pontiac. I know a lot about Olds, Buick, and Cadillac, mainly because those are the Brands I have owned, 2 Olds, 3 Buicks, and 5 Cadillacs. Current ownership, licensed, insured and on the...

    1150 Link & Sync Question

    I'm not sure what the Geometry is all about You can place the Pin in the hole closest to the Transom, or even throw it away. I added an Arrow tp the pic pointing to the AV Plate

    1150 Link & Sync Question

    The motor looks a little low, but it is also trimmed in at the moment. The Rounded edge of where the Transom meets the bottom concerns me. That too will send water upwards, and steal a few MPH from the top speed. Getting rid of the wing thing should reduce a lot of that Water Fountain back...

    Spreading Manure, again

    Go back a year or two, and read BT's original Fawning of this prop. The Informercial, which is all it was, was so poorly done, and full of errors, that it wasn't even credible. A couple of weeks later they brought forth a Cleaned Up Infomercial with 'revised' Data and Comparisons, but it was...

    OMC 3.8l dying at high rpm and weird cranking issue.

    All engines that discharge the Exhaust underwater face this, In outboard an Idle Relief is in the design to let exhaust gases out above the Waterline at Idle and low Speed. I/Os tend not to have them above the Water Line. 180 is too high for a Raw Water cooled Engine. I wonder what Thermostat...

    1150 Link & Sync Question

    Unless you want to start filling and drilling holes, not much? I guess an Jackplate could be used to raise the Engine and provide some setback as well. But lets see what the Straight Edge reveals. Boats with shallower Vees tend to be a bit Skittish on turns. Those Fins... Myself I would remove...

    Okay, I think I see the Spray problem, Those wings bolted to the Antiventilation Plate. If the Engine is a little Low, the Water will come above the AV Plate, hit the Wing things and... I think the engine is a little low, but the Picture is taken from too high up. A pic level(camera not aimed up...

    1150 Link & Sync Question

    Spray like that could mean the Engine is trimmed in too far, and/or is too low on the transom. I suspect a bit of both. What hole is the trim/tilt rod in, counting the one closest to the transom as #1? I love the Snarl the Inline 6 makes. Did you have a Tach working? If so what RPMs at WOT...

    OMC 3.8l dying at high rpm and weird cranking issue.

    Back Pressure, as all the Exhaust outlets are underwater and full. Vapour Lock is where Fuel Boils in the Fuel Line between the Tank and the Fuel Pump. All liquids boil/flash at lower temps as the Atmospheric Pressure is lowered. Lower pressure in the Fuel Line is what causes the Atmospheric...

    Spreading Manure, again

    Last year there was one guy on here constantly claiming every Prop made before this Pretzel, was inferior. When the Prices were revealed to be near the Orbit of the Moon, he probably thought, it must be even Better than Imagined, with a Price like that... I wonder what his connection to the MFG...

    OMC 3.8l dying at high rpm and weird cranking issue.

    That spring thing is called an Anti-Syphon valve, required by USCG Regulation. It is supposed to prevent the tank from draining it self, but the Lower Pressure provided by the Fuel Pump is supposed to unseat it. There is no removable tube inside the fitting on the tank? Not a great design if you...
