    Am I getting water of of fuel path Properly 150's J150VXCIS 2001 carbed 150'

    My 140 Evinrude didn't, neither did my Merc 115 or 150 FICHT, and, my VP I/O certainly doesn't. The I/O has a Water Filter, but I replaced it 4 yrs ago, after 16 yrs and there wasn't any water in it.

    Having that Ethanol Garbage blended to the Fuel, certainly doesn't help in Marine Apps

    Stuck between pitch

    You do realize that what makes Power in a Car/Truck application, is rarely transferable to a Marine Engine. I am referring to the Bumpstick. I have seen far too many Boats with warmed over engines, where the Owner, is boasting that his motor can make X number of HP at whatever Rpm. Maybe it did...

    Spray from the outboard

    Have you run it as it is Currently set up? If so, did at any time do the Prop lose it's Grip on the water? If not, I would go higher. If it did, then a hair lower. Raising an Engine higher, reduces the Ability of it to Lift the Bow, simply because of less Leverage. Higher Trim Angles are...

    Spray from the outboard

    Seeing your Prop, and that is doesn't look like it has any Cup, keep an Eye out for Ventilation, where the Air from the Surface gets into the Blades, resulting a jump in Rpm, and often a drop in Speed

    If there is water in the Tanks, then it needs to be removed. You might have to take the tanks out again, in order to get all the Water to the Pickups. A bit of Ethanol might help diluting the water. I would not recommend trying to use a Vacuum to suck any water out through the Filler tub, as...

    Spray from the outboard

    You have quite a bit of Setback, and as a Starting Point, the AV plate can be about 2 inches higher than the Hull Bottom. Putting it flush/even, like you would if the Motor was mounted on the Transom, would result in it being too deep.

    Stuck between pitch

    Without knowing the Engine's Power and Torque Curves, it becomes a problem to determine a WOT Rpm Range. A stock 5.7 of that era of OMC had a WOT range of 4200-4600 rpm. Yours is a Vortec, and even stock units have a range of 4400-4800. OMC Stringer Drive. That Drive was Overstressed when...

    1975 9.9 sea horse

    A 2 stroke engine requires 3 things to run; 1: Fuel and Air, in the Proper Portions 2: Compression, in the Crankcase, to get the Air-Fuel to the Combustion Chamber, and in the Combustion Chamber 3: A spark at the correct time Your Engine is deficient in at least One of these Items. More...

    Stainless Prop Film

    Looks like a non-Polished SS Alloy that was Nickel/Chrome Plated. Boating in a Lake/River with a low PH Level(acidic), may have stripped the Plating off

    Is it getting fuel? Spray a little Premix into the Carb, and see if it lights. Don't spray Starting Fluid, as it is bad for 2 Stroke Engines that pass Air-Gas-Oil through the Crankcase, as it is very good at washing Oil off the Internals

    1995 25hp Johnson 2 stroke, what are the best years for the 25 hp?

    Personally, I like 3 cylinder 2 Strokes as they are far better when it comes to Exhaust Tuning, which can result in better Performance and better Fuel Economy, than a Twin, or in the case of larger Engines, a 4 Cylinder

    To me, he is saying just set the Points at 0.20", get the motor running and go boating

    Increased Rake, holds the Bow higher, at lower Trim settings. Props with less Rake are better for raising the Stern

    Did you set the Points using the Feeler Gauge as stated in the Book? If you did, it should be Fine. FYI: The Armature Plate does rotate as the Throttle is moved.

    What is necessary for jet change of .002 of an inch?

    Can the Spark jump a 3/8" Gap. You will need a tester similar to this Heat can cause Havoc with Ignition Components. Have you tested for spark, at the time of problem, or once you and the boat were back home, and everything has cooled down?

    1975 9.9 sea horse

    Welcome to iboats A 1975 would have a Magneto Ignition. You tested for spark. Did you use a Gap Tester similar to this set for about 5/16" of an Inch? A Spark at a 0.030" in open air means nothing. It takes a lot more Voltage to jump that Gap during the Compression Stroke. Speaking of...
