    First of all, what is the WOT Range for that Engine? Is is the Engine in Good Mechanical Condition and in Tune? About 5200 rpm, which is still likely on the low side

    Wakeboat bans

    I find that music relaxing. When I hear that Fecal Matter called Rap, I want to grab a Bat and start Smashing Things

    Wakeboat bans

    About 42,000 ft from a Shoreline, sounds about Right Won't be able to hear the Pathetic Noise they try to say is Music either. If they were playing Black Sabbath, AC/DC, Judas Priest, I would be tapping my toes, but not the Fecal Matter that seems popular these Days

    What make and computer system to replace my Windows 10 before October 14 ?

    Windows 11 looks very Ugly and there is a Reduction to the Options that appear when Right Clicking. It will take many hours of tinkering in the Registry to make it Right again.

    79 Chrysler 115 Won't go into gear

    Noise? Like clack clack clack....? These motors are either In Gear, or Out of Gear. They do not use a Friction Clutch, where there is Slippage, so NO Easing it into Gear. Try unhooking the Shift Cable, and Shifting it at the Motor, make sure the Engine is running, or have someone turning the...

    How much slip does your prop have ?

    This was with a RAKER, a vented Prop. The Enertia(has Adjustable Vents) is quicker out of the hole and has better top end

    I used up all my curse words yesterday

    The 3.6 in the XT5 is a completely different engine than the 3.6 in the STS, even the displacement is considerably different

    I used up all my curse words yesterday

    Same goes for my XT5, the Intake has to come to get at any of them. The Auto Steelerships leaned on GM to make Cars/Truck that not DIY friendly, forcing you to take it to a Shop, hoping you will take it to the Stealership. Nothing like a $1500 dollar bill to change the Plugs, $1200 to replace a...

    How much slip does your prop have ?

    Without Slip there would be no Thrust. How much is acceptable, depends on Hull Design, Weight of loaded Hull. If you drop Pitch and increase Diameter, Slip will get lower, but that likely will not result in higher Speed. On a Planing Hull, Slip will be at its greatest upon Initial Acceleration...

    1998 Evinrude 60HP 2 stroke Slow Max Speed

    'spark is good" is not an answer to my Question. A lot of people will take a plug out, ground it and check for spark. A spark under those conditions doesn't mean there will be spark in the cylinder under compression pressure. Air is a fairly good Insulator, and the more Dense it becomes the...

    Mercury 75hp on aluminum 16’ Starcraft

    The Nemesis has been a very good seller, at my Dealers Parts Counter, and the Parts Manager has told me that a lot of buyers say good things about it. Nice Place to go boating. I hope there aren't too many Rocks to hit Returning to Sea Level, you might need more than a 2" increase, 5000 ft is...

    1998 Evinrude 60HP 2 stroke Slow Max Speed

    Welcome to iboats Are all Cylinders receiving a Spark that can jump a 3/8" gap? Are all the carbs getting Fuel? That is critical, as No Fuel, or not enough Fuel, means not enough Oil for that Cylinder. Also who is this "They" you mention twice in the Post? The Tach would get its Signal from...
