    OVERHEATED HEAD & CYLINDER PICTURES. HOW MUCH TROUBLE AM I IN???

    I'm a commercial clammer and we go out 365/7 weather permitting. After irregular high tides the bay has random floating salt marsh hay and I managed to snag enough which covered my water intake for no more than 30-45 seconds. The engine stalled and was red hot to the touch. After cooling off it...

    CAN HEAD GASKET BE REPLACED WITHOUT REMOVING ENTIRE ENGINE FROM HOUSING (15 HP)

    Several years ago I pulled the entire motor to change the pistons due to scoring. This time I just want to change the head gasket but before I begin I was hoping someone had done this without removing the entire engine from the housing. I take pictures whenever I do a job and when I checked my...

    Need Help Identifying Mystery Recoil Pull-Starter (Pictures Included)

    Cannot i.d. this pull starter. It has the same numbers (6E001) on both the inner-metal section and also on the plastic section (that holds the rope). I thought it was a Johnson/Evinrude but these numbers don't make any sense. I hate to trash this since someone out there probably needs one since...

    Starter Switch On 15 HP Johnson Needs Replacing

    My Starter Ignition Switch, that is located on the front of my 15 HP 1983 motor, has been glued together 3 times and may not take a 4th repair. Is there a readily adaptable push button switch that can be substituted since new ones are $200 and there are no used ones available? I see other marine...

    How Do I Rejuvenate Dried-Out Keel Rollers ???

    My center rubber rollers are still solid (no cracks) but they are very dried out because boat was removed for repairs and the sun got to them over the last 2 years. Rather than replace them, I want to try and use a lubricant, penetrant, etc., but not something that will make them decompose...

    2hp or 3hp For My Canoe

    I recently got a 12' flat-back aluminum canoe and want to put a 2 or 3 hp motor on it. I have a lead on two small Johnson outboards: a 1990 3 hp Johnson (2 cyl) and; a 2 hp Johnson (1 cyl - 70's). Does anyone know the weight difference of these motors? Although the 2hp should be okay perhaps...

    What is best additive for Long Term Storage?

    I have some older outboards (and other motors, too) that I hope to 'someday get running' but that day will likely not be for a year or two. I use Seafoam occasionally in my everyday motors but wondered if something like Mystery Oil would be better for long term storage. The motors in question...

    Need (bottom-lighting) ideas for darkness boating in shallows

    I am a commercial clammer who needs to go out 365/7 and oftentimes we need to go out pre-dawn or are returning after sunset. We travel in the shallows and we need to stay in narrow channels at low tides. I need lights capable of penetrating 1-2 feet of water and that can light up the bottom in...

    No Numbers Stamped On Gearcase Gears

    I need to replace some parts in the gearcase of my 1964 18HP Evinrude Model 18403D but the gears in my gearcase have no numbers stamped on them and none of the major suppliers show my specific model. The only number I could find was on the propeller shaft which has the part number of 305192...

    Tilt Tube Removal - Engine Impossibe To Raise Or Lower

    My outboard is almost impossible to pivot (up or down) and the tilt tube needs to be removed and cleaned or replaced. There is no major rust on the exterior of the tube. The outboard steers fine and the steering cable moves freely through the center of the tube. Does the outboard need to be...

    Need Help Identifying These 'Shock Absorbers' (see pictures)

    I got these Mercury shock absorbers (or dampers) as part of a large lot of surplus boatyard stock that I bought and hoped someone might be able to identify them. There doesn't appear to be any casting numbers on them (other than those on the rubber grommets). Previous threads seem to indicate...
