    Help with motor height adjustment

    I understand your comment sir and would agree but with the significant dead rise at the transom, I don't think that is necessary and if he does what I said he will be out of options other than unbolting the JP and lowering it with respect to the transom. Let's see what happens.

    Engine RPM drop

    Don't have that engine but I bet the spark advance mechanism is binding, either in your engine linkage or something under the flywheel. On smaller Merc engines, timing is around 0 before or after TDC at idle,....matter of fact you set the idle 675 rpm by changing the timing, while at WOT it's...

    water pump and shift shaft position

    Well if your control is in N, engine off, and you can spin the prop freely, you are half way there. If you shift into F gear and the prop resists turning CCW viewed from the rear but ratchets as it turns CW you have it right. Don't shift into R without the engine running or somebody turning...

    distance traveled per revolution

    Pull this up: https://www.go-fast.com/Knowledge-base/Find-your-prop-slip/Prop-slip-calculator It's all right there. Zero slip is a screw turning in soft wood. No such thing as negative slip and a propeller in water will always have some slip....fast fishing boats at WOT setup properly can be...

    Help with motor height adjustment

    Tell you what...before you spend any money on another prop, drop your engine to the first hole on the JP (I assume you have 4 holes on the engine's clamp bracket and you are all the way up in #4) and loosen the bolts on your JP and drop it all the way down.....bolt everything back up and take...

    Need help identifying this (i believe) 50's-60's boat please

    I don't know if Lone Star copied TMs blue prints or vice versa but the two did have very similar aluminum hull designs.

    Boat submarining question

    On the wake thing, it is the following water from the lead boat's transom that is forcing the following boat's bow into the back side of the lead boat's bow wake. I have experienced it before and had enough sense to control my boat, understand what's happening and figure out how to pass such a...

    Lower Unit?

    First wild guess would be old gas. Has a way of really making a good engine run crummy!

    Best prop

    Before you invest in a prop that may not solve your problem, How about a couple of pictures of your boat, inside and hull and the engine to transom area including having the engine down in the position where it is when you are having the problem...picture...worth a thousand words. Back in the...

    1986 115 tower of power cylinder wear

    "All just button it up and run it, the funny thing is if I never saw in there I would have been totally happy with a little lump in it at idle. but now it will be in the back of my mind everything I run the thing." "We" do tend to do these things to ourselves....leaving well enough alone! If it...

    Lower unit will not go all the way in

    Shift into F gear and slowly turn the prop ccw...the direction where you can rotate the drive shaft, not the overrun clutch direction, while "jiggling" the LU with hand pressure. 3/4" is about the length of the powerhead to drive shaft "spline" engagement....seems your teeth aren't lined up...

    60hp Merc intermittent power loss

    Get a companion and go out with the engine cover off. While they take care of the helm, you get back there and start wiggling fuel lines including the line from the tank, including both ends. Then take the cap off again and see if it makes any difference. On outings where it worked and didn't...

    1999 90 hp 3 cylinder 2 stroke mercury no power, sounds fine

    Well an air leak is a great idea.....you can start with your fuel lines. If they are OEM they are way overdue for replacement.

    What's wrong with the general purpose prop that came on it?

    1999 90 hp 3 cylinder 2 stroke mercury no power, sounds fine

    On checking the fuel pump and was ok, you may have missed THE smoking gun....diaphragms loose their plasticizers over the years and get stiff. A stiff diaphragm doesn't pump much fuel. The hole is probably a vent or a manufacturing necessity, like "freeze plugs" in an engine block...have...

    2003 Mercury 25 HP won’t crank

    Agree with Sea Rider on the fuel pump not sucking. If the tank vent were closed and the pump was pumping you would have a collapsed bulb and couldn't get it to puff up so that you could squeeze it. There are fuel pump repair kits numerous places, may be here.

    Trim tab feedback

    If you have deep pockets and smart tabs aren't smart enough for you try the hydraulically adjusted tabs...you can put them down like flaps on a 747 and raise them up and out of the way when on the Pad! Another option is a ported prop (if yours isn't ported) in helping the hole shot. Would be a...

    Help with motor height adjustment

    One has to realize that water leaving the bottom of the boat returns to the surface. Rate of return dependends on viscosity of the water and boat speed. Second point is that boat hulls are seldom level when running in the water. With that said, and the fact that once the transom passes over...

    60hp Merc intermittent power loss

    Passing that test and running smoothly tends to tell me that you have a clog in the fuel distribution system somewhere. The fuel pump sucking couldn't dislodge the culprit but the extra pressure Pushing rather than Sucking did. I'd revisit fuel filter in the engine, and fuel strainer in the...
