    I am at the end on my rope with trying to install my throttle and gear selection linkage at motor.

    got it....hoping it could lead to something you can investigate further... I'm surprised at the multiple differences in and between the 1989 25 and 20 hp motors with the linkage ...... but, I wouldn't think merc used different cables.....

    I am at the end on my rope with trying to install my throttle and gear selection linkage at motor.

    and this is the 20 hp. It show's different arrangements just for its motor.

    I am at the end on my rope with trying to install my throttle and gear selection linkage at motor.

    I'm seeing multiple configurations for the 25 hp motor. Including a remote control attaching kit.. I have no idea if this is your problem, but maybe look into it.

    I am at the end on my rope with trying to install my throttle and gear selection linkage at motor.

    I'm not on facebook. Is the throttle bracket on the 20hp the same as the bracket on the 25hp?. I'm just asking, 'cause I'm not there....I would assume there is no difference, but I've learned to double check everything..

    I am at the end on my rope with trying to install my throttle and gear selection linkage at motor.

    so, is this the stock configuration that came with the boat? or is this something being replaced? if so, is there anyway the cable is wrong?

    Engine support while towing.

    yeah...they're transom savers, not TT savers, or outdrive savers.

    Engine support while towing.

    aluminum pontoon transoms don't like excessive flexing either

    Engine support while towing.

    it's the transom that's taking the brunt of bouncing and flexing when trailering. That's why they're called transom savers. If the motor could be balanced evenly over the center of the transom and kept there, and the transom was exactly vertical, you probably wouldn't need anything, except for...

    Engine support while towing.

    I've got a '21 merc 115 hp, CT motor. I'm sure your 90 weighs close to mine. Previously had a merc 60 on my pontoon and didn't use a transom saver, never really noticed it bouncing much. But this 115 bounced like crazy, so I use a transom saver. I also learned not to use the tilt lock for...

    2.75's are they just bad designs?

    yep..good luck with that. It Just depends on your goal. you can tweak, but that can get expensive. ahicks is right. When I went from my 60 hp to my 115 hp, I only gained 6 mph. But I did get the tube hauling performance I wanted, but at a significant gas cost.... I tore up my 3 blade, 16x12...

    2.75's are they just bad designs?

    ok..well...so the plate is below the motor pod but just wonder if that 3/4 center toon is causing flow issues. If it was me, Id be trying to see where the plate is in relation to the water when at speed. Anyway. these are my #'s on the props I've run. 24', twin tube(25"), '21 Merc 115 CT. Dealer...

    I've tried to find your specific model. Is it a tri-toon?

    Should I replace my surge brakes with electric on my boat trailer?

    just fresh water for me. Minimal towing. Launch in the spring, retrieve for a lake trip, back home to launch, then retrieve at season end..not much exposure. Brakes are 7", 10" wheels. shouldn't matter I wouldn't think. No rust issue, just couldn't get uniform performance from the new surge...

    Should I replace my surge brakes with electric on my boat trailer?

    I totally redid my karavan's surge/drum system when I bought my used pontoon about 7 years ago. '01, tandem trailer with a completely neglected, non-working brake system. So on went brand new brake assemblies, coupler/master cylinder, rubber brake lines, bearing, races and one new axle.....The...

    2.75's are they just bad designs?

    And I learned that reducing my prop pitch, or blade #, or diameter ( they ALL effect max rpm) my top end speed would drop but my rpm and "torque" would be better.... generally speaking.....

    2.75's are they just bad designs?

    ah, propping a boat......I cannot, nor will, tell you what prop as propping a boat as I found out can be.....interesting. And I knew basically what that involved. I'll say this: I put a new 115 merc. CT motor on my 24', twin tube (25") pontoon. Normal operating rpm range is 5000-6000 rpm. They...

    2.75's are they just bad designs?

    yep..I wouldn't drill holes yet. If it's one thing I've learned about pontoons in the last seven years it is they are more susceptible to ventilation and prop height compared to a standard hull. I just have a twin tube, the motor is a long shaft, and before I lowered it, I couldn't trim up at...

    2.75's are they just bad designs?

    is the motor at a correct height? lowering my then new motor in 2021 on my 24' pontoon just 11/2" fixed my ventilation issue...
