With the lower unit removed you aren't pumping water. The water pump is in the lower unit and must be submerged in a drum filled with water or connected to a water hose with an adapter referred to as "Muffs".....a pair of 3-4" rubber cubs, joined by a spring steel bar and containing a female...

Agree on the pad and height could be part of the performance desired. Problem I have is recalling the rule of thumb from the big guns on here, especially a guy from Coral Gables, Fl. I think, with a 300 Johnson on a Donzi I think among other things: 1"up from even per 6 inches of setback...

Answered this elsewhere.

To ensure that your problem is only electrical, squeeze the primer bulb when trying for WOT RPMs. If you get them new fuel pump kit and probably should do a new fuel filter and cut the old one to see if black or tan specks/chips are in it and if so change your fuel lines from the tank all the...

Question answer is Yes. The 8 pin connects to the Commander 2000 and 3000 remote controls to name a couple. The latest released version of the manual covering the 2 stroke 3 and 4 cylinder 60 Jet thru 125 was in late 1990's and covers 1994 and later engines. All engines have the same pin out...

I don't remember when and on what engines Merc introduced their 40kV (unloaded) plug voltage. Would assume the difference may have occurred at that time.

Solace 4 blade SS. Just bought one and it does what it says it does. High quality and in the 13" version, was less than $275 free shipping for my 19P. It does a lot of ventilating at level trim angles just above plane making for high prop slip numbers. Tilt the engine all the way down and...

Is the live well a structural member? What if you seal off the inputs and use it for storage? I have 2 on my current boat, did that and wound up with them full of needed boating accessories. That will give you some additional room.

I work the 3-4 cyl 2 stroke Merc arena. My last 2 engines were 2002 models. OEM manual I had with the 3 cyl was for engines in this category and the manual starts with the 1994 engines and goes on out to the end of production in 2005 I assume...since I am interested in 2002 year models. So I...

Obviously a supply problem. If something works that is fed from the breaker panel, then one would assume the panel is getting power, and therefore all breakers on the buss are being fed. A wiring diagram would help to isolate the breaker (my guess) feeding what doesn't work. Sometimes...

Your comment: "Ok thanks. I guess I could always use the evinrude for 5 years and then switch the motor to a merc or yamaha when the time comes correct?" If that's the way you really feel, why risk it. Buy what you want in the first place and be done with it, rather than have the guilt...

Main problems you hear about are: Before you start, a manual would help in addition to what I am posting....iboats sells them as does ebay. 1. Separation of the lower unit could be 4 obvious bolts between the LU and mid section. You may have a 5th bolt so mark the position of your zinc trim...

I went after a clog because of what you said. What could have happened, with you not indicating that your impeller is 4 years old and is of unknown operational/storage history, is that a piece of an impeller blade could have broken off and is clogging a water passage. Or you could have gotten...

Totally agree and that applies to motors that are seldom used. I use my boat a few times a year and both first start and length of time between outings applies. Once running for that outing, the rest of the starts are immediate.

Put the engine on muffs and turn on the water pressure. Disconnect the water pressure/tell tale hose at the hose barb on the engine block that feeds engine block water (pressure) to the dash gauge and tell tale. Take a piece of wire and clean out the hose barb...determining that it's not...

Not necessarily marine related, but when replacement time comes, I use what makes sense and is available. If that is substitute, hose barbs and auto fuel line works for me...inland lake, not over 40k acres, no salt water usage. Every time I see an old Mercury Mark XYZ I marvel at the aircraft...

Yepper.

SWAG: When filling, one inserts oil from below the gearbox and continues to fill till clear, solid, non-bubbly oil exits the vent just above the antiventilation plate. The upper drive shaft seals are beneath the water pump so there is some room for LU oil to expand at the top of that chamber...

Cavitation is minute air pockets formed when the oxygen is pulled out of the H2O mixture called water. Reduced air pressure, aka vacuum is what does this and in your case I'd say the rough character of your surface is the smoking gun. I have no idea as to how it looked when originally...
