    Nitro boats use balsa wood?

    Nitro is a fiberglass bass boat division of Tracker if I recall. Maybe Tracker uses/used it in their aluminum boats. My neighbor just bought a 2017, Tracker 2072 Grizzly and it is all aluminum. You can probably find an access port adjacent to the transom where you can reach in and feel/have a...

    Motor opinion

    My service manual for 60 through 125 hp 3 and 4 cylinder 2 stroke, loop charged Mercs. says expect problems when compression is less than 120 PSI. I'd say you are problematic if you are conducting the test properly with accurate equipment.

    Need torque for prop nut

    Yes. I had the 1971 85 triple I bought new and I don't remember the exact number but the shafts are probably the same diameter so the nut should tolerate the same ft-lbs. You don't want it loose.

    Fuel Starvation?

    Go 2 steps farther: 1. Disconnect the fuel line from the engine and squeeze the bulb. If using a connector, have someone depress the center pin (so that fuel will flow when commanded). You should get a good fuel response and no tan crystal/crunchy material.....nothing but clear fuel. 2...

    Update on my electric fuel pump installation.

    Thought I'd get the boat out of the shed and run it up since it's been about 3 months since I was out with it. Set the engine vertical, hooked up the water, turned the key to ON. Could hear the fuel pump running, went back and felt the bulb and it had pumped it up nice and firm. Went back to...

    Fisher sv-19 gt w/ 150EFI prop pitch?

    In your water test keep in mind your normal usage. The WOT pitch determination should be made with normal usage weights/loads/type usage (hole shots for water skis/tubes/water toys) and all. When boating at other times, like when you are alone then just adjust the throttle accordingly to stay...

    Mariner 60hp motor identify help

    My OEM manual for 60 Jet through 125 loop charged 2 strokers indicates that anything below 120 should be of a concern. My current 2002 115 hp currently has 129 on 3 cylinders and 130 PSI on the 4th measured by the mechanic at the dealership where I bought it a couple of years ago. No telling...

    My boat in saltwater

    When I was growing up I fished both types of water. I only had one outboard boat and non galvanized trailer but had 2 sets of fishing tackle. One reason was the different baits for the different types of fish but the main reason was the salt attacking the box and contents plus the rods and reels.

    My boat in saltwater

    Your trailer will be the main concern, especially the wheel bearings. Folks in S. Texas usually buy galvanized trailers for longevity and either have a live axle whereby the grease flows through the spindle, or have at the least Bearing Buddies.

    Is it possible to sail from mexico to texas currently?

    Last thing I read concerning Texas ports was that Governor Abbott was toying with the idea of inviting some of the container ships sitting idle in the Pacific rim to come to Texas to unload.

    More testing on Sharrow prop...

    My latest prop purchase, SS 4 blade Solace 13+x19 was $275 free shipping. Works great with WOT single digit slip, 115 Merc on 2002 Crestliner 1750 Fish Hawk.

    Alumacraft 14ft Weight and Motor Capacity

    Back in the '60s a 14' Alumacraft, model number unknown...we didn't deal much in models then....you saw a boat, liked it, had the money, and drove it home thing..... with the one piece hull with rounded chines, 3 bench seats and a very modest side, very modest console mounted to the gunwale on...

    Prop Question

    Once you get in a range of props, like 13+ for 75-125 hp engines and 14+ for 135-250 engines for a couple of examples, whereby the diameter is limited by the allowable distance between the prop shaft and the Anti Vent plate, the change in diameter has to do with the blade shape and geometry...

    Long or short shaft

    Those engines sit low. I had a 1956 18 Fastwin I bought new so I know. Get any vintage sales brochure and check pictures of those old OMCs sitting on a trailer with the engine in the normal running position. You'll see the AV plate below the bottom of the transom. I never dug into the...

    Permatex Aviation Gasket Former.-

    For metal to metal head gaskets I always use Copper Coat product, in aerosol or brush/can......made especially for the purpose.

    Evinrude 130HP switching from 3 blade to 4 blade

    OT...... in following along with your postings over the years, for a guy who apparently has an advanced degree or so in engineering or math, your Avatar/Handle just blows me away. Apparently you quit the rat-race and decided to do what you love. Good for you.

    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...
