    Steering Wheel

    Agree, probably white plastic around a steel rod core for the outer diameter and a horizontal bar with mid section bulge connecting the center to the cable drum. Not familiar with the Malibu. If windshield, front deck, dash, and full cross seat with back rest cut down in the center, it...

    Help prop an old boat?

    The tach is a must to start. You didn't say you had power trim so you select the thrust angle with a pin location on the transom bracket. After you get the tach, load up with your 4 people and the dog and adjust that pin for the tilt angle of the engine with respect to the transom position...

    Bad Transom?

    Another possibility is that the lower unit hit something while backing up putting undue stress on it and the transom. I would say a "hands on" test of the integrity of the transom, and any possible damage to the engine mounting brackets or skeg or prop shaft would be in order.

    Four Winns hull strength

    A Sea Ray hull failed? A friend had one and was working on it and had the steering console apart as I recall and I was amazed at the thickness of glass even in the console.

    That's what I thought.

    How to find pitch and diameter of a stainless steel prop and is it left or right

    I bought a new 1972 18' Caravelle tri-hull bow rider with a 125 Johnson V4. It had the factory alum. prop. On Sundays the family went to the lake for water toy fun. On Mondays, during my lunch hour, the prop would go to the prop shop for repair....almost every week. In 1973 OMC came out with...

    Mercury 50 hp, no power at prop, engine runs fine.

    Hitting a rock really has nothing to do with the shifting mechanism....if the prop is doing its job as the sacrificial element. As Jimmbo said, remove the prop and inspect the hub for signs of damage especially if it has a replaceable plastic hub like is popular these days. If you have an old...

    Need help with Hull crack in Aluminum Lowe Boat

    I bought an old Starcraft 18' Holiday I/O and restored it. The bow eye wasn't pulled out like yours but it was worn probably 2/3 through the thickness of the loop. Took it to a welding shop and they fixed me right up. I had the boat for many years after the restoration and that weld held up...

    Prop recomendation for mercury bigfoot.

    I think I verified that the lower unit is infact a prduction 75 through125 HP lower unit which runs a 13+" diameter, 15 tooth (as I recall) prop of varying pitches. Would think that the prop for a big foot would be 10 to 15 pitch area depending on load to be pushed. I think Q'Buoy runs a 115...

    Moving the filter

    Problem with the filter on the inlet of the fuel pump is a condition known as "vapor lock". The fuel pump sucks on the fuel tank causing a partial vacuum /low pressure area. When hot, lowering the pressure on a line full of fuel can cause it to boil filling the line full of gas bubbles not...

    Solenoid clicking.

    That's 10 across the hot terminal and case of the starter. A clicking solenoid is caused by the key switch telling the solenoid to energize. It does and sends current to the starter. The starter starts sucking on that current but the battery cannot supply the necessary probably 100 amperes...

    1986 mercury 115 2 stroke inline 6 bogging at full throttle

    5/16 will run a 115 and probably a similar 125. 3/8 on larger engines. With what you said and the history of the interconnecting fuel line and bulb your fuel filter should be full of particles. Change it and cut the old one open.

    1986 mercury 115 2 stroke inline 6 bogging at full throttle

    You didn't mention an onboard (the engine) fuel filter. Even if it was changed I would replace it with what I see in the last picture. One thing you didn't mention that is an easy try is to squeeze the primer bulb in the fuel line when it wants to bog. If it recovers you have restrictions...

    Should the prop have any play

    Brain fart!!!! Sorry. On the amount my serv. man. for my 115 is 55 ft-lbs. He said he had a 120.....close enough for me.

    better to be at the low end or top end of RPM?

    My take, on pressed in rubber hubs, is that the shock is mitigated by the rubber interface. I had one plastic/brass replaceable insert hub prop and it had no room to give. It didn't stay long on my engine.

    Prop recomendation for mercury bigfoot.

    Prop shop time for you. Prop shops sell and repair props. They also can have a loaner plan whereby the purchaser tests a prop and if its not right, they talk over the change necessary, you test the suggested prop and if it works you buy it. 2 caveats to that: Prop will be more expensive than...

    Should the prop have any play

    The lower unit contains an "overrun clutch" that is a saw toothed set of gears that allows the engine to slow down when decelerating but allowing the prop to follow the forces acting against it, by flowing water, as the boat slows. As the F gear (only has this function) and the "clutch dog"...

    Raising the Transom?!

    Well if you had a 15" stock OEM skeg on your engine you wouldn't need to jack ut up 5" to accommodate your 20" OEM skeg. Since you said you are doing the whole transom, it will all be one piece and you won't have to worry about the strength of a joint there as you would if you were just...

    Raising the Transom?!

    You have a 20" skeg engine on a 15" transom. 5" is your number. What you have will run but performance will be hindered by too much skeg in the water producing unnecessary drag. Also that extra 5" will put you in the mud, or catch on logs, or moss or lilly pads etc. Make a pattern of your...

    Decarbing Yamaha 2 stroke with Seafoam

    Decarb procedure should have numerous answers on any www search engine. Just type in the word. Years ago, when a lot of the old salts that help to make this site what it is today, were able to participate, it was talked about frequently on here and the archives should be full of...
