    Smartrail / Splash Rail for Trihull?

    Can't help you there but you just caused me to recollect another of the reasons I didn't like my tri-hulls....If you were heading N for example and the wind is blowing up decent waves from the East, with the helm on the Starboard side of the boat, you got wet as the Starboaard Sponson threw a...

    Water pump rebuild after 11 years and 600 hours

    On my last boat I had a temp gauge and as you, I could see the poppet open since the engine temp would drop to the ambient surface of the lake temp. The boat in my Avatar was 2 years old when I bought it. First time out I honored the "No Wake" area near the launch and everything was working...

    Water pump rebuild after 11 years and 600 hours

    We each have our own idea as to how we maintain our equipment. I'm a "don't fix it if it ain't broke" guy especially on water pump related work due to the accessibility. If I were going 25 miles out in the ocean I would surely have a more conservative attitude than the couple of hours I putted...

    Question about the 1990s era 75/80 and 90 lower unit swap to 100/115 and 125hp

    That's true....the 90 had a 2.33 and the 115 2.0 lower unit gear ratio.

    Question about the 1990s era 75/80 and 90 lower unit swap to 100/115 and 125hp

    Don't know about that model era but it may be/probably is related to the 2000+ year models. I had a 2002 90 3 cyl. and a 2002 115 4 cyl. and they seemed to be the same except for the extra cylinder extension making the cowling taller. The OEM service manual showed reference to the 75 (Jet) all...

    cupped prop question

    Yea Jimmbo we both know that if its cupped, besides the progressive pitch, you can just look at the blade and clearly see the tip of the blades are bent up slightly....I say slightly as I read prop design literature explain that the amount of cup depends on the total prop design and you can have...

    What kind of boat is this?

    I had several of them when they were popular....1970-80's. It's a trim-hull and I didn't like mine especially for Sunday trips after church with the family aboard. But at the time that was all that was available where I boated and shopped, other than an open aluminum Skiff/John type boat...

    cupped prop question

    Yes. More bite = more load on the engine = drop in "work function" for a given fuel input.

    cupped prop question

    I guess I missed something over the years. Other than Turning Point Hustler aluminum prop mfgr. the only cupped props of which I was aware were "most" SS props. My experience with cupping is better bite at high trim angles and in sharper turns it helps to prevent "prop ventilation"......the...

    cupped prop question

    .....and the peak of the torque curve is usually much lower than the max RPM point.....at least that's the way it is on 4 stroke diesels and gassers....one of the things that I always found interesting is that OEM outboard mfgrs. never posted their engine torque curves......except for one...

    Tiny boat performance help

    It's a "Moment of Inertia" thing......Foot-Pounds. You have the pounds in the items lifting capabilities which is constant but when you add "feet" to the equation it becomes more effective! Its like sliding a pipe over the handle of a wrench trying to turn a nut that won't budge!

    Water in lower unit

    Plus seals on screws removed when changing LU lube as a potential culprit. If soapy water doesn't show anything, get a tub of water and with the LU pressurized as stated..like 10 PSI, submerge the LU and put it in different positions while submerged. Some seals are bi-directional....lip one...

    Ratcheting Into Reverse - Mercruiser Alpha One Gen 2

    Exactly. I rescued an 18' Starcraft Holiday with a Merc. I/O that had been badly abused. When I got the outdrive apart, the rear of forward gear and front of the clutch dog were just like Chris said. The problem with that is that there isn't enough material in the right dimension to stay...

    Anybody Running NGK BUZHW-2 Plugs?

    I can't believe this conversation from 2012 appeared today but it did. For what it's worth, the "rig" posted in my pictures was the boat I was running when I snapped the picture in my Avatar......back then.

    suzuki prop vs turning point 4 blade prop; looking for advise

    I agree on looks and later on in my boating years, I liked the shiny SS props on my black Mercuries. I guess seeing the shiny prop, in my mind, spelled "performance" whereas the OEM black aluminum just reflected "so-so" performance....so the TPs didn't last very long and wound up sitting on the...

    1980 Mercury 9.8 110 HP outboard

    The idle screw (low speed ratio adjustment) is set ok at the normal recommended starting point. The spraying premix into the Venturi and no response is confusing.....tends to move the suspected problem from a dirty carb. as the source of the problem. The starting with fuel sprayed in the...

    Jackplate yes or no

    My only reason for a YES answer would be if you do a lot of shallow water running. With that pictured addition, I'd expect your other performance would probably be hampered.....but with the rig as stated, it isn't going anywhere very fast and that would mitigate any "new water flow into the...
