    Evinrude 130HP switching from 3 blade to 4 blade

    Ski boats around here, including Ski-Nautique use 3 blade bronze. Old period Chris Craft and such running Greymarine 6 bangers ran 3s also. Never saw one with a 2 blade...but that's here and you are there. As the old TV show goes: "Different Strokes for Different Folks". Grin

    Will carport help mold/mildew issues?

    I think anything containing Chlorine is a must for initial prevention and subsequent clean up. I keep my boat in my shop but the buildings on my farm get an algae buildup on the North sides, regardless of material. I spray with soap and a good amount of bleach in water solution and by the 3rd...

    1992 6 hp 2 stroke dies when reeves increased

    Running out of fuel would be my guess. Clean carbs, change internal fuel filter if it has one, disconnect fuel line at the engine and either remove the connector or hold it open and squeeze the bulb and see if you get a goodly amount of fuel out of the hose. Engine that old may need new fuel...

    No Power When Cold - 1985 50HP

    Agree on 3 new coils. On the resistance, copper is very temp sensitive as to resistance per unit length. If it was a winter day, I wouldn't worry about it. At least you have continuity and the Stator is made up of laminated iron, copper, and epoxy....not much to go bad there.

    1970 River Queen Houseboat new owner here!

    Beth, I admire your spirit. Think the worst and be happy for the best. Having done a fairly large restoration with a limited budget, no experience, and few tools, I can tell you the journey is worth the result. Besides any job done to your best is self fulfilling. Go get 'em gal!

    No Power When Cold - 1985 50HP

    A Ferrite around a high speed circuit (wire), like a CDI that dumps the capacitors in microseconds (0.00000X seconds), is placed there to "choke" the harmonics and radiated energy from the wire helping to prevent radiation to other parts that don't like electrical interference caused by high...

    Mercury Oil drain plug size

    14mm is the thread OD. 1.5 is the thread pitch....1.5 mm penetration per revolution......that's a coarse thread (comparing to SAE coarse-fine type ratings) for that small a thread.

    Who has installed Helicoils ?

    Well the coil has to remain in the tapped hole so it is deliberately designed as an interference fit. With that said, if its a certain length relaxed, and stretches for an interference fit, then obviously they will be longer installed than sitting on the work bench. They come in different lengths.

    Evinrude 130HP switching from 3 blade to 4 blade

    "The less blades on a prop…the more efficient it is. This can’t be argued with. When comparing like for like." That's why Karl equipped his engines with 2 blade props with lots of surface area....till the Phantom Black paint and 3 blades, Merc. 1000 first production 100 hp 2 stroke outboard...

    No Power When Cold - 1985 50HP

    I don't know if those Classics of later design used Capacitor Discharge Ignition (modules) or stayed with the conventional points and coil. At idle you can be missing out on half your cylinders and not realize it. The surge you mention tends to lead me to ignition....a plug is trying to fire...

    Revolution 4 XP prop

    No, it's a 2002, like the boat, 2+2 and runs and hole shoots like a dream.

    Revolution 4 XP prop

    The boat is a Travis Marine Fishmaster 17 1/2 ft aluminum laid out as a bass boat configuration. The bow is conventional, popular, V'd front deck, rather than flat like a John, but at the transom, there are 3 steps to the hull, the center one being about 10" wide. Kissing 50, with the 24 XP...

    Revolution 4 XP prop

    I didn't tuck in for my hole shots. I had the trim putting the engine vertical or slightly trimmed out. In coming out of the hole it was hammer down on the throttle to the firewall, I got grip and then ventilation as the load on the prop was such that it found ambient air a path of least of...

    Prop ventilation?

    Measured from where? CL or area that lets the most water across the blades which looks to be at least an inch different. Pros and cons to either dimension.

    1986 ELPTO Mercury 90 Enrichener valve question

    Probably but easily enough solved. Get some tubing and connect to each port with the opposite port open. Exercise the function, blowing into the end of the tubing and experience the results.

    Swapping Short and Long Shafts between outboards

    Off topic but what you see in your picture is why Mercury Marine, through their extensive testing in the late 1950's testing at Lake X, Florida, added shock absorbers to their engines and engine kill switches later so that when the engine kicked up and the RPMs were significant, preventing...

    Revolution 4 XP prop

    It was the Ballistic. Funny way they engineered the blade tips but really grab and hold running at WOT high trim angles.

    Happiest Day of Ownership !!!

    Very nice "large trailerable" boat. Design seems to be very well engineered and thought out I like bow compartment functionality and access being on the side leaving room for access to the below area. Surely good times are ahead.

    Revolution 4 XP prop

    Had a brain pfart. XL should have been XP for extra performance which is what I got.

    Swapping Short and Long Shafts between outboards

    A series of engines a lot of times share components and only make slight changes to fuel/combustion parts to vary the HP rating. The question is where is that break point and why would the spline count be different on a SS drive shaft when you only have a low percentage of power changing. If...
