    Im going crazy! Mercury Keikhaefer Merc 110

    Welcome to Iboats, Not familiar with that precise model. Usually all motor discharges water through a peeing port located around the right side of the lower pan or upper middle leg ? If not, seems that discharges water straight through the prop ? Happy Boatig

    1986 Yamaha 25hp doesn’t run good under a load

    Was the motor running strong before or it's something that developed afterwords ? Being a 35 year oldie the current prop must be shot or in the process to become so. Start with a prop hub test to determine if the prop is working right. The primer bulb will remain fully firm only when it's fully...

    2009 Yamaha 15hp 2 stroke pull cord problem

    Check if with at least with 25NM each, hope the bolts has not been stuck salted already, if so will think that the torque remains OK but won't be torquing anything. CRC will remove most of the carbon built up that has been collected through the boating years and will smooth out the motor...

    Many moons back wrote an essay about tall plates gap motor installations for anything that floats which was shot right after posting with a lot of associated expletives by the big shots that likes boating with short plates gap motors found in large HP ones but keep throwing both motor types in...

    Thermostat housing hole.

    Getting the right prop by simple looking along measuring a rig it's just a reference as deck load, worse if variable has not been taken into the least consideration and will knock down that equation. Will also depend entirely if (1) wanting a fantastic hole shot with slight less top end speed or...

    DVA stator testing

    Electric/electronic components have 3 stages : Works spot on, are fully shot or failing with intermittent issue, the latter being the most difficult to troubleshoot precisely, should be tested when at load pushing a boat. Also could be a CDI, switch box, ignition coil issue failing...

    Hydrofoil for Inflatable Seamax 430

    Fins are garbage collectors and manufacturers making good money with them, useless on portable motors with tall gap plates. What you need to do is : trim motor to 90º, distribute deck load evenly, have a spot on transom/motor match, install a maximized prop for whatever floats to run towards...

    Hydrofoil for Inflatable Seamax 430

    Good to count with an electric air and foot pump, large Sibs must ride fully inflated to their working pressures to get the max out of them. Don't buy any doel fin or any other fin type, save the money for some cold ones. Useless installing one on top AV plate when already having prop aeration...

    Some issues : Which air pump is being used to inflate the tubes and keel ? if manual, it's a hand or foot pump, if electric can you select the amount of inflation pressure ? Regarding the unven stretched fabric, it's a factory flaw, these guys have not learned so far to glue well what needs to...

    Yamaha 15 mounted too high

    Playing with different manual trim hole settings won't dial any improvement, when the combo runs on plane the motor needs to work trimed at 90 deg on transom along a correct deck load distribution for a nice water performance. But if the motor is powering way high on transom will cancel any...

    That's why its imperative to test the combo on flat calm no wind water condition whenever possible, will assure runing the motor at it's max throttle grip on a flat water surface, then going next for a prop maximization for motor to run at its max wot rpm factory stated. Why should you go that...
