    1979 115 hp 6 cyl inline 2 cycle timing/carb adjust

    Curtiss, Small engine mechanics will not help you with your thoroughbred motor. And your motor is a thoroughbred. Get the manual and follow it exactly, or you will not have a motor.

    1985 157 Forester Phantom Sport steering assembly

    I would expect a standard rack and pinon steering system will replace that. You may need to modify the cutout in the dash, as the new rack may not be compatible with your pinon or housing. Just so you know, steering system OEMs seem to want to phase out selling replacement cables. They want...

    1979 115 hp 6 cyl inline 2 cycle timing/carb adjust

    The Mercury 115HP inline 6 was one of the most popular and successful motors ever built. The last one was built in 1988. You clearly need the service manual for it, as it has specific link and synch procedures, and does not usually act as you have described. Once you get the carbs clean and...

    Store under tarp ?

    As long as the tarp keeps the water out and is not sealed, it should be fine. Alternatively, can you flip the dingy over? If so, no tarp necessary.;

    I'm just about ready to sink it.

    Also, when you removed the powerhead, the shift lever could have lifted enough to separate the splines. They are only held down by the shift slide and linkage. If the shift slide rubber was stuck in the shift slider, the slider is bolted to the powerhead and could have pulled it up.

    1979 115 hp 6 cyl inline 2 cycle timing/carb adjust

    I think 1979 was the changeover from distributor ignition with 1 coil to Alternator Driven Ignition (ADI) with 6 coils. Timing is unique to each type of ign. So what do you have? Did you replace carb gaskets, floats and inlet needle and seats, when cleaning them? If not, it is a real good...

    I'm just about ready to sink it.

    The shift arm under the carb should be facing port, when the shift slide is in the center of the slide track. That should be neutral. When the throttle handle is in neutral, the cable that is extended the most is the throttle cable. The shift cable will be about 1/2 extended. When you move...

    Where to pass the fuel filling hose and vent fuel hose?

    Most fuel pickups unscrew from the tank. I cannot tell from the photo whether your does. I had a vent that was pressed in, that I needed to swap with the fuel pickup, which was threaded. The vent fitting would rotate but not come out. I ended up drilling it out and threaded the collar to...

    Where to pass the fuel filling hose and vent fuel hose?

    From the original photo, I had though the fill and vent were in the rear of the tank. That makes them easy to route thru to the engine compartment. Cutting or notching a frame is much better than cutting or notching a stringer. However, the way the picture looks with the black lines, (fill...

    Ignition Fuse Pops, Weird Issue

    What year MerCruiser? When you say cutout switch, do you mean shift assist switch on shift linkage?

    Where to pass the fuel filling hose and vent fuel hose?

    Scott says "running to the back will create a dip in the line and you will never get fuel in the tank". That is simply not true. Many boats (including mine) have that configuration. The fuel filler hose is wire reinforced, quite rigid and doesn't sag easily. I also do not recommend cutting...

    Upgrading, or downgrading?

    Gee, go to a boat show and walk around in a 21 foot outboard model and then a 21 foot sterndrive model. Do you really want to trade a roomy interior of the OB model for a cramped cockpit, and the extra 700 pounds of weight of the sterndrive, to get a full swim platform? Sterndrives also...

    Where to pass the fuel filling hose and vent fuel hose?

    Run the vent and fill hoses directly to the stern. Then route them to one side of the transom. The vent should go straight out the transom and the filler up thru the cap.

    Anyone know of MOSFET Rec/Reg installed on an outboard?

    Looks pretty good. The original was fastened to the cooling water jacket to help keep it cool. I would recommend the same.

    Fuel Filter??

    Those older carb models had a small cylinder-shaped paper filter in the fuel connection to the carb, plus a porous filter stone on top of the mechanical fuel pump. Did you replace those? Antisiphon valve is another likely candidate. Also, on my'88 SeaRay, the fuel tank pickup had a filter...

    There was a rubber pad-type product that you would put over the transom, and then clamp the motor over it. It was supposed to reduce vibration. It was only for small HP OB's, like yours. Not sure of the name.

    Anyone know of MOSFET Rec/Reg installed on an outboard?

    Is it potted? If not it may not hold up to the corrosion inherent to the environment.

    Anyone know of MOSFET Rec/Reg installed on an outboard?

    You can tee off the yellow wire for the tachometer. Does that VR have the capacity for the charging system of your motor. You should make sure, I know the later models have dual 20A VRs. I think the older models were less amperage, although some were single 40A VRs..

    Upgrading, or downgrading?

    That sterndrive will get you about 42MPH, wide open. It will drag it's butt to get on plane compared to your OB engine. Also, the cockpit size difference between a 19 footer with a sterndrive (and doghouse), and an 18 footer with an OB, is nothing. Actually the 19 footer maybe a bit more...
