    Merc 80 Jet Enough for my 1860??

    Most dealers won't install higher than the coast guard plate ratings due to liability as already mentioned. Most insurance companies won't insure it either. I have read where people have had the transom reinforced and built up, then took the measurements and did the math to figure out the new...

    Merc 80 Jet Enough for my 1860??

    I would go no less than a 115/80 and a 150/105 would be better for a 60" or bigger bottom. A 115/80 will push it ok. If setup correctly, speeds should be around 34-36 on top end. It will do fine for 1 to 2 people if loaded light. It will struggle to get on plane as you have seen with more...

    25/20 outboard jet on a 12’ Jon?

    You would be better off to get a 14ft and no less than 40in bottom. A 25/20 will push it, but will be underpowered and take a bit to plane out. Keep it as light as possible. Jets push the rear of the boat to the side in turns and will put the back corners under water in hard turns on a narrow...

    Gas Tank placement

    I would try it with the fuel tank in the rear and keep the battery up front. Should keep the weight distributed fairly well and you can move the battery later if you need more in the back. With everything up front you are probably plowing a lot of water.

    Jet outboard troubleshooting

    Wear on the impeller and liner will affect rpms. I've also heard as these new 4 strokes break in somewhere around the 40 hr mark they produce a few hundred more rpms. Definitely get it checked out to be sure, anything other than the liner, impeller, or shoe should be covered under warranty if...

    Pump bearing grease hose

    I've always had good luck ordering through them. I have always had the part numbers of the parts I needed though. Ship to the house in a couple days. You can go through the diagrams at this link and look up everything you need for any model, just need your pump model. Click on menu, hit small...

    Decreased WOT speed and RPM's

    Have you sharpened and shimmed the impeller recently. Can easily lose several hundred rpms there. In turns it could be getting enough air to allow it to spin up more. Is the gas all new and fresh or topped off with new. Just a couple ideas!

    1856 alweld with 150 efi jet

    Draft I would say 8-10 inches. If it is setup right and running the way it should, it should be able to run down to 2 inches without a problem. Depends on the area you are running, rock ledges and such you want a little deeper. I run a lot of gravel areas and if it is not sticking out of the...

    1856 alweld with 150 efi jet

    Great setup in my opinion. The wider the bottom the better it can handle weight. It will draft maybe an inch or so deeper than a 115/80. That 150 will be about 105 at the pump. It doesn't sound like much difference in hp but the extra torque carries a load much better and hops on plane in a...

    UHMW Jet Intake Fins

    I think the first solid hit would rip them from the pin holes, possibly allowing bigger rocks and debris into the intake causing more damage. The reason I say this is because I bought a set of the uhmw side skirts from James River. The first time out I went over a stump and it twisted one of...

    Combo seat swivel AP/B class?

    https://www.attwoodmarine.com/store/category/swivl-eze/lock-n-pin These are the ones that I have. The posts fit snug in the bases. I have never had them pop out while under way or on the highway. I usually remove the ones on the deck before trailering though. When they are in the sun and it's...

    Transom Outboard Jet Spray Deflectors

    Here is mine, original one is at the top. The bottom one I made out of .125 aluminum plate. Most spray happens when water goes over the lip of the shoe. It follows the u shape bend on the pump and shoots back to the transom.

    Combo seat swivel AP/B class?

    I have had the 3/4" push in pins in my boat since 2002. Have 2 posts with seats that can be moved to the deck or in the floor. Ran a 115/80 jet with them for 10 years and now have a 250 Pro XS and have had zero issues with the seat bases or posts. They do not lock but also don't just freely spin...

    2010 Evinrude Etec 115 Jet Pump Motor Revs but wont go. Help

    First take it to a lake or river for a test run. Jets do not like a lot of debris in the water. If you were helping after the hurricane everything was in the water. Anything sucked up to the intake will cause a loss of power. It doesn't matter how much you rev it, if it can't pull water through...

    Motor Shaft Length with 20" Transom, Need Advise Please

    Need a 22" transom for a 15" shaft motor. A 20" shaft motor needs a 27" transom.

    Transom adjustments for jet

    It would be best to have the transom built up. Jackplates don't usually work very well with jets. Too much setback, causes excess spray and pushes motor weight farther back. The transom will sit deeper in the water and the bow will ride higher. If you are going to use a riser, Outboard Jets...

    Greasing Problem 2013 Mercury 60/40 Jet

    Does sound like a blowed out seal. Grease guns build too much pressure. Have to be very careful with them and pump slow. The low pressure plunger type with the tubes are the best to use, very hard to damage the seal with them.

    Suggestions for choosing an outboard?

    That is speed with 2 people at most and very light load. A 115/80 drops off quick when you start loading it down. When I say forever with a heavy load, I mean 100-150 ft. Start as far back as water allows, full throttle, watch the shoal getting closer and closer, seat up your ***, waiting any...
