    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...

    Trailer brake system opinions

    Well I was doing just that....at 35 mph on a state highway going through town. Obviously you want to set your brake controller to cause the trailer to pull against the tow vehicle (slightly) when stopping and that has to be set every trip for the existing conditions .......otherwise you would...

    Revolution 4 XP prop

    Nobody hit on this having seen it early this morning and decided not to do what I am fixin to do. I had several SS Ballistic props and 2 were XL versions, all in the 21-24P range. The XL versions had a lot more blade area and a lot better thrust with much better high end bite and speed...with...

    Trailer brake system opinions

    Its a matter of physics. The electric brakes stop the trailer....they could stop the whole combination if adjusted too tight/kick in too soon or too much or the trailer could theoretically be totally disconnected from the tow vehicle and still stop. The surge braking system relies on the tow...

    Using a Manual jack plate to fit a 25” shaft motor

    Recalling the "big guns" on here years ago said 1" rise for 6# of setback so 10", about 1 1/2 inch inherent in the setback so you could/should put her on and set it at 3 1/2 inches up for starters and then adjust as necessary. How you boat will come to play in that....the faster you run your...

    Engine Mount Trolling Motors

    Slightly off topic but your comment about smoking people out, that was before 50:1 fuel mix....24:1...quart of "motor oil" to 6 gallons of "gasoline". Somebody else will have to jump on whether or not you can decrease your oil ratio when using today's TC-W3 (Two Cycle-Watercraft 3rd iteration)...

    Bearing Buddies

    My 2002 Crestliner has a Heritage custom trailer and probably the company that rebranded with the Crestliner name to match the boat. I had never seen anything like what I saw at the end of the axle for a water proofing device. I always used after market Bearing Buddies on previous boat...

    Trailer brake system opinions

    I had surge brakes on one trailer. Single axle, ample tongue weight...at least 500#, 18' fiberglass, tri hull, deep V, bowrider, lots of glass so weight made for a good ride on the water. Tow vehicle a 1972 Chevy stationwagon. Recalling, I think the tongue of the trailer was extended the...

    Which Direction to Curve Water Pump Impeller Blades

    Prop ventilation?

    Besides the other good ideas, if OMC is like Mercury in that HP range the props suited for it are between 13 and 14" diameter. Divide either by 2 and you wind up with a number larger than 6...your reported depth of your prop shaft......but if your measurement was at the centerline of the boat...

    3 Blade or 4 blade prop?

    To my surprise, adding a blade and dropping an inch of pitch going to the Solace did little to drop my WOT RPMs while enjoying the rest of the reason for buying the prop. Whats funny is that I dropped WOT RPMs a couple hundred in the process but still got that performance. Possibly the 3 blade...

    Evinrude 130HP switching from 3 blade to 4 blade

    I run like you do. I replaced a 3 blade Laser II with the Solas 4 blade dropping one inch in pitch. The solace performed beautifully and I have no aspirations to take it off. Go for it.
