    Tub rinsing motor

    I recently began to use a rubber made 100 gal tub to rinse the motor after a day on the water instead of using the muffs. I did so for two reasons. One to save water and to make rinsing the motor a much quieter event. However, the last two trips out I noticed a drop in water pressure at higher...

    rough rpms at low speed

    Upon having to operate the motor at 2000 rpms or so to establish the 5 mph speed limits, the motor runs rough. By rough I mean the motor tends to vibrate more then normal due to a very light yet, "continuous" [if that makes any sense] hesitation or stumble between the motors normal vibration...

    Cold start issues

    It would appear that my motor no longer cares to start right away when attempting to do so only after the motor has not been used for a few days. Such as when trying to start the motor in the early A.M. while on the launch ramp. However, once the motor has warmed up a bit it will start each and...

    bouncing tach needle @ idle

    I was wondering what might cause the needle on my tach to jump around at idle. The tach does not read accurately at idle. It shows 1000 to 1100 rpm at idle which I know is not correct. Plus the needle will bounce plus or minus 100 rpm or so while reading an idle speed of 1000 or so rpms. The...

    air/fuel mix adjust

    Hello everyone, I replaced the air/fuel mixture screws with brand new ones due to the needle tips being damaged from overzealous seating practices by the previous owner. Starting at 1 1/2 turns out from fully yet lightly seated, the motor begins stumbling and coughing brought on by a lean...

    Prop free play.

    Hi everyone! Not sure if this is the correct forum to post this question. How much free play, [ability to slide forward and backward on the prop shaft] if any, should the OEM rubber hub prop slide upon the propshaft with the prop nut properly torqued?

    Propshaft side play

    I recently replaced all of the lowerunit bearings and seals. I was able to adjust the end play of the propshaft to about .002" to .003" by installing a forward gear thrust washer of correct thickness. With use this play has increased to .007" +/- .001". However, the propshafts side to side play...

    Trim/tilt pump diagram

    Once more I made the mistake of relying on my Seloc manual. Upon disassembly of the trim/tilt pump I find my particular unit [The trim/tilt pump is the two wire, two ram model] has parts not mentioned in the Seloc manual. According to Seloc my pump unit should have three internal springs and 3...

    H20 pump pressure

    Hello forum, I notice that when I have been running the motor at a fast rpm for a few minutes that the water pumps pressure begins to drop from 10 to 12 lbs. psi to a psi of 5 lbs. where it stays steady. Once I drop rpms to around idle for a couple of minutes and then run the boat above 4000...

    water pump psi within range?

    Hi all, I have a question I am hoping one of you might help me with. The question I have regards the amount of pressure the water pump should be able to generate under normal circumstances at both mid-range rpm's and at WOT. According to the 0-30 psi scale pressure gauge I recently installed...

    Question regarding seals

    I notice that Seloc manual says to install seals with either the lip up or lip down depending upon where the seal is being used. However, I believe the seals they refer to are seals that only have one sealing lip. Where as most of the seals I have encountered now use the more popular double lip...

    Forward gear shims

    According to the HSG number stamped on the lower unit housing [assuming the location of the stamped number is under the oil fill plug] the foward gear should have a minimum of .008" of shim material under the forward gears roller bearing "outer race". Upon pulling the "outer race" from the lower...
