good luck finding one(2.5 200), seems like the price on the newer four strokes have driven the price on good used two strokes up. Look on craigslist cities around big fresh water lakes. I've been looking for a 200 for a friend of mine, found a bunch of 150's, even a 175, but 200's are getting hard to find. The 225 Opti seems to be the most common used engine for a decent deal, you just have to deal with the weight

spot on spare, that's why i keep this on standby, when my oil injection fails, i am only four bolts away from being on the water again...

jason, i'll keep looking over this way.

Thanks, Phat. I might be over in your neck of the woods tomorrow looking at a 94 2.5L 200. Spare i agree Optimax's are everywhere now that i have decided against one. I have found a couple 2.5L 200s around town, my uncle from Louisiana is checking on one for me too. Hell i even found one for $950!!

I'm not talking about the 250. I'm talking about a 2.6l Yamaha. But even a 250, If you get one that has a good crank and just needs a piston or two isn't too bad. My 225 needed one new piston when I got it. It also needed a crank but I got that for free. I had the one cyl bored out and re-ringed the other five. I rebuilt the carbs,replaced the oil pump and water pump and thermostats. And it's been good ever since. I'm closing in on 400 hours.

a couple months ago I installed an electric oil pump conversion for a 2.5 merc. It uses an electric motor to run the merc mechanical pump. It all fit under the cowl with no real modification to the engine. When I go to work on Monday will try to find the papers for it.

Here you go. I honestly don't know why Mercury never made a replacement bronze gear for the crank.

But what if you lose battery power or somebody turns the battery switch off while running? I assume the 2.5L will run without a battery after its started. Do the 2.5L have an alternator?

Also what should i read on a multimeter on the plug leads? On my 1985 Johnson 150 it had low voltage on two plug leads. May be contributing to why it was so thirsty and had no power.

Priced out a Mercury binnacle control $334. May find an aftermarket cheaper but i would like to stay with all Merc controls and gauges. What about a prop, whats a good starting point?

Is this the electric oil pump?? www.marinesolutionswi.com/index.htm

That's it. Ironicly enough my Yamaha rep helped develop this product. It uses the merc oil pump and keeps all the merc alarm sensors. If I had a 2.5 Merc that's what I would use. Sure beats wasting expensive oil on premix.

$400, pricey, but a lot better than tearing down the engine & putting it back together.
with another plastic gear.

nice info , capt pete

Stuck in the house today. As if the pouring rain wasn't enough i have a killer toothache now. I hope to look at the outboard tomorrow weather permitting.

I like the EOI. But my only concern is if it loses power. The power wire is connected to the starter solenoid. Like i stated earlier what if the battery gets disconnected? $400 is a bit pricey but, when compared to carb cleaning and plugs changes associated with premix, i think it might pay for itself. Even just in the oil cost.
