I am now the owner of a 1994 Mercury 2.5L Offshore 200. Compression was 120 +/- 2psi on all cylinders. All the oil injection was removed and they did not have it. Not sure if i am going to replace all of it and run EOI.

The tilt tube is pretty rusted, and the previous owner took all the latches off the cowling and the seal and used bungee type latches on the cowling. New decals wouldn't hurt but it looks good as is. All in all i think i did ok paying $1200.

On the way home we stopped at Bass Pro and took the dogs in with us for a quick look around. First time i have even been in Bass Pro and i found it crowded.

Right now i am building a stand to run it. It did not come with controls or keys,etc. How do i shut it off once i get it running?

congrats, welcome to the merc fold. i have an old piece of a wiring harness that i hooked up to a generic key switch. it makes it alot easier starting & stopping. i bet bass pro was packed given the weather we've had.

I figured out which terminal in the harness shut it off.

Motor sound really good. I think i might have upset some neighbors running it at 10:00 at night.

Put a thread on the local forum to see what some of the dealers can do on a package deal for rigging. As for a prop i have a Rapture 14.25x21. I am thinking its too much pitch.

It had a tee in the water outlet hose that i assume was for water pressure. Should i keep it or just plug it?

As for maintenance i have already replaced the spark plugs, and i plan to change the lower unit oil and water pump, then clean the carbs. Still wondering about the oil injection.

I found that a SS 14.5 x 17 was a good all around prop for my engine (1991 200 hp 2.5 Merc) It pushed my 2500lb 21' Cruisers, Inc at an honest 42-45 mph seemingly effortlessly. I still have that prop on my engine and will be using it when I put the engine on my V21 later this year.

I still have my OEM oil injection hooked up, and it works fine, but truthfully I was going to unhook it and run premix. After seeing that electronic unit I think I'm going to bite the bullet and get one. I figure that $500 is far better than several thousand for a new engine.

since the po had the oil injection disabled, i'd run premix. i would definately have a water pressure guage. it also should have a temp sensor. i would run both. i like the pressure guage because it lets me know a problem is developing. with a new water pump, you should have between 10 to 13 psi @ 4000 rpm. when mine starts only showing 7 to 8, i know i need to change it soon.

I might go ahead and run water pressure, as for water temp the Mercury Flagship gauges only have a C-H type gauge. I would rather have some numbers, but its no big deal.

Looked up parts for rigging, and i bout had a heart attack when i seen the price for a outboard to remote harness $280 for 20'. That might be the only used component i use on rigging if i can find one used.

The Rapture props are no longer made. They have been replaced by "Apollo". The 21 might make a spare. $280 for an Apollo stainless prop. Both Rapture and Apollo are Michigan wheel props.

Destroyer if you decide to run premix i can take that oil injection off your hands.

Speaking of 225 Optimax on a V - should run 50-55 mph. Nice.

If I decide to go that direction you're first in line.
