    Jet Drive Outboard Motor Debris

    Gee, don't jet drives pull most of the water straight up from the bottom? I would not expect the keel to affect that. I would expect the keel to affect a prop drive, as the prop pulls water from under the hull.

    1987 Mercury 150 xr2 Blackmax Newbie Help

    Gee, the impeller may be good, the carbs may be clean and the timing may be right. However, the motor setting for any length of time often causes or worsens the condition of the carbs and impeller. Any of those not working or not set correctly can ruin the motor.

    Converting jet to prop

    You might check the Sterndrive Engineering (SEI) website. Your motor is new enough, I would think, to buy a new gearcase from them.

    1987 Mercury 150 xr2 Blackmax Newbie Help

    Gee, if it were me, I would change the gear oil, replace the impeller, wearplate and two gaskets, clean the carbs and check the ign timing.

    Mercury 1982 70hp Bluestripe Foot/Gear case

    Crowleymarine will have the parts list for your motor. You should be able to get the part number for the gearcase. Now, whether you can find a used gearcase for your motor is a different subject. Alternatively, you could try a prop with 20% more pitch.

    Am I hurting things by not running WOT?

    You want to prop your boat so it will run at max recommended RPM at WOT. That gives keeps you in the motors powerband properly. Lugging the motor is bad on several levels. Once you have that, pick a speed that you like and run it. As for best economy, solidly on plane and trimmed near max...

    Livewell design

    Why do you have the drain connected to the fill hose? All it will do is clog it with fish guts. You could connect the drain to the overflow hose, low down in the hull. That makes sense.

    Is a 4.3 Mercrusier Waterpump the same as a 4.3 Chevy waterpump ?

    The timing cover on my '88 4.3LX looked to be automotive grade, as was the oil pan. I say was, because it rusted thru.

    Is a 4.3 Mercrusier Waterpump the same as a 4.3 Chevy waterpump ?

    Also, the backplate on the marine waterpump is stainless steel.

    Carolina Skiff 198 DLV loose steering at steering wheel

    Look under the dashboard. Rack and Pinon steering will have a long bar-shaped mechanism. Rotary steering will have a round steering mechanism.

    Carolina Skiff 198 DLV loose steering at steering wheel

    Gee, if that happened to me it would be the loose nut on the steering cable and behind the steering wheel. But that is just me!

    Is there a filter between the primer bulb and the carbs? Is it clean?

    Losing power on 2000 2 stroke Johnson 70hp

    Pump primer bulb at high speed and see if she will keep running. If so, it is likely a fuel pump or fuel line issue. My SeaRay I/O did that and it turned out to be a partially clogged filter on the fuel pickup.

    They are usually made of marine vinyl. Marine vinyl is avail at many places, even Amazon. A lot of marine vinyl sellers will send you samples for free or a nominal charge.

    Mecury BlackMax 175Hp, Constant Beep and Overheating

    Those motors are not made to run without thermostats. Is the poppit valve working properly? It should open at about 2000RPM and allow a whole lot more cooling water thru the block. Put a torque wrench on the head bolts and check 'em for tightness. Sometimes they can get loose and allow...

    1989 Johnson 50hp fuel pump fittings

    You should be able to blow thru the fuel ports in one direction only due to the check valves. The port that allows air in obviously means fuel in as well. The pulse port will be sealed.

    Jet Drive Outboard Motor Debris

    Jet drives (no matter what kind) are lower in efficiency than prop drive motors. i.e. a 105 Jet Power OB will have the block from a 150HP Prop drive. You might take that into account when choosing the power of the motor.
