    Johnson 70hp stainless steel prop installation

    Marine dealers that have been in business for a very long time usually have accumulated an assortment of used props and thrust/mounting washers. I bought a used prop from one such business and took the prop and a box full of used washers out to my boat, found the correct hardware to fit the...

    loose wires 90 HP Mercury 3 cylinder

    Yeah. Tan is OT sense wire. If you ground that wire the horn will sound if the key is on. OT sensor is embedded in the water jacket plate on the rear of the block, about mid way down on the left side...to the left of spark plug #2. Possibly the sensor failed (shorted) and the PO just...

    2001 Mercury 150 Saltwater Series (carb) midrange bog after extended running.

    The problem I see with the above comments is its midrange, not WOT. So what in a fuel system would clog at midrange only, and only after hours of operation? And is it the whole engine or are you loosing a cylinder....and how could the cylinder workfine for hours, then clog, then increasing...

    Can I use a Johnson/Evinrude tank on Merc outboard?

    Interesting comment, just pun or factual. If factual, what's the mechanism......I know its jest since OMC was big block torque and low RPMs vs Merc. 1 HP/cuin and 6k WOT.......and NOISY...had both over the years.....but my 2002 115 is very quiet.

    Replace 2002 115hp lower unit

    The lower unit with the 6 toothed R gear is identified with a casting change: Get behind the engine facing forward and look down at the center, rear of the LU, the raised area that extends to the rear of the unit. In the casting, about 2" from the rear end is a diagonal in the casting whereby...

    Hole shot to plain very very slow

    I found this for reference: https://www.smartmarineguide.com/L51899307 That rig ought to catapult out of the water in the hole shot and run 55-60 range at WOThrottle. If the above suggestions don't yield answers, you might weigh the boat as the foam flotation may be saturated if it sat out in...

    Mercury Spitfire X7 vs Solas Titan HR 4

    You realized what I was going to tell you as an aid to making the right decision. The Ports that the Solace doesn't have made the shot difference and when popping a skier out of the hole they help that too....I currently have the Solace HR-4 on my 17.5' Crestliner Fish hawk (Merc 115) because I...

    Service manual for 75-125 hp outboards says 55 ft-lbs....for a number. As stated, good and tight.

    1999 mercury 100hp 2stroke info?

    It idles a tad rough because up to 1800-2000 RPM (depends on how your linkage is adjusted) you are only running on the upper 2 cylinders....but they fire 180* apart like the old OMC "alternate" firing 2 cylinder engines that were smooth running for 2 cylinders. The lower 2 cylinders also fire...

    Prop Slip

    The gofast.com calculator is simple. 2.33 is 2.33, RPM is in HZ...5500 is 5500, prop pitch is in inches...19P is 19. Push the title block over Max Speed and you get max speed in MPH....that's a screw turning in wood, not a propeller turning in a movable volume....water. Jump over to your GPS...

    Tritoon vs Deck boat

    That deck reminds me of 1970's tri-hulls. Only ones that would take a good chop were the "trihedral" hulls where you basically had a deep V mono hull with sponsons....1970's vintage 19' TriSonic Trihedral is a good example. Most of the boats under 18' were shallow draft and light weight like...

    115 Pro XS Command Thrust on a pontoon - prop?

    As we all know you can't use GPS when you are in flowing water unless you know the velocity of the medium and its relationship to you....aka are you parallel to the stream, or on a bias? Course what you can do is to calibrate your speedometer to GPS in standing water and then use your...

    1995 Talari 190 4.3 with 1.84 ratio 205HP

    I recently bought the Solace 4 blade that I mentioned. In the verbiage furnished by Solace they spoke of bow and stern lifting types of props. Their 3 blade, other parameters identical is in the bow lifting arena like would be used on a bass boat and their 4 blade is made for water toys and...

    1995 Talari 190 4.3 with 1.84 ratio 205HP

    What's your RPM with the borrowed prop at 41? Is the borrowed prop "ported"......holes under the leading edges of the blades? How's the hole shot with that prop? Its interesting that you are getting more speed and RPMs simultaneously which is hard to understand especially when you said...

    '22 Mercury 115 Pro XS, best prop?

    Agree raising the engine off the transom even one hole (3/4") can make a MPH or more difference. You have to have the right prop to raise the engine off the transom since you are inviting ventilation at early trim angles and when up like that you need the trim out to get the hull out of the...

    '22 Mercury 115 Pro XS, best prop?

    I guess your gear ratio is 2:1 like my 2002 2 stroke 115.....seems to be pretty much an industry standard for that HP. If you are running over 35 MPH for a number, trimming out always reduces the wetted area of the boat and increases RPM and speed as you indicate due to less hull drag. I am...

    Prop Selection Advice

    Ebay postings list the condition when they post the ad. If new is says so, if new but opened packaged, for some packaged items, like it was opened for display purposes but not used, it will say so, if pre-owned it will say so. I've purhased about 400 items from them when I was building my N...

    Can I run my Mercury outboard without gear oil?

    I bought my first boat at 15. Didn't have a car but mom let me use hers. I didn't know s....from Shinola (a brand of shoe polish popular back then). So don't worry about it. Have a question, ask. If you don't like the answer or answerer, forget it and get on with your life. Good Luck.

    Prop Selection Advice

    I shop ebay often for lots of things. Purchases are guaranteed by ebay, not the seller so you are covered. On returns, different sellers have different rules on things like prop returns. Usually its if you mount it you bought it....seller's comments....reason being that seller has to sell it...
