225 Optimax opinions

[jasoncooperpcola]

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 They have been replaced by "Apollo".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.

Jason. I kept thinking about it, turning it over and over in my mind. I like the idea of not having to premix gas, but I hate the thought of living under the "will I lose my engine because of a failed plastic gear" cloud. So
I ordered an electric oil injection unit today. http://www.propelledmarine.com/oil_injection.htm I don't know what, if anything, is or is not required of me to remove from my engine. But if I have to remove the present oil pump are you still interested? My engine is a 1991 Merc 200 2.5L.

I believe the EOI uses the old oil pump.

What we need is a boat mounted 50:1 premix unit. Something that you pour your oil into, and it mixes the oil with the gas at a 50:1 rate, then pours it into a remote 5 gallon fuel tank, which the fuel is then drawn out of by the outboard. The remote 5 gallon tank serves as a backup in case, the unit fails you dont immediately burn your engine up.

Maybe i should patent this idea???
