Thanks, that is what I needed to know

I have a 1994 Mercury Black Max 150hp 2.5L EFI Xri with serial number 0G052601. It there anyone out there that can tell me if it is a 20" or 25" and if it has 178:1, 1.87:1 or 2:1 gears. I keep...

So quick question, is it possible to add a trim gauge to the black max? Tired of looking back to make sure the motor is done, guess I could add a mirror, LOL.

So, I finally got to take it out and run it through the paces yesterday and I am happy to report it runs as it should, idles in neutral at 950 to 1000 and in gear at about 750 to 825, going off the...

So I'll bring this back to life. Took the boat to a boat shop and they found 2 issues.
1. water in the VST, but funny thing was no water anywhere else because they check the tank, lines and filter....

Okay, now I have to learn how to check the link and sink. Yes it already has the jumper wire on it

So finally got a chance to put some fresh gas in and take it to the river. Right off the bat it started up and idled in the water, took it off the trailer and tied it to the dock, left it idling...

Guess I should also have mentioned that I am going off of the tach on the dash, so it may not be super accurate. I am not going to do anything until after I fill up the tank and take it out next...

Update: Got the ECU back, installed it and pulled it out of the garage, hooked up the muffs and started it up. Immediately noticed a difference in the sound and thought sweet it is fixed, then after...

Well just heard back from Simon Performance. The did find bad drivers for injectors and fuel pump. So they fixed it and it is on it's way back. Keeping fingers crossed that between those issues and...

I'm tired of messing with it, so I'm sending it off to Simon then, if it checks out okay then I'll move on, if not it's there for the repair.

Actually JOE, I already removed the ECU and would just as soon send it off to be check out and repaired if need be. So who do you suggest?

Well JOE54 you where correct, wasn't the switch boxes. So where do you suggest I send the ECM for test and repair. The place close to me doesn't repair outboards ECU, they gave me a number to Simon...

Sounds good, I do have a place 30 minutes from me that repairs ECU's. SIA Electronics

SSSHHHHH I didn't want to say that out loud and it doesn't appear they are available anymore, or at least not at my first search, not to mention the sticker shock. Switch boxes already on the way, so...

Did the ohm's test on the stater and trigger, both came in spec, so ordered 2 new switch boxes, we will see

So I am still messing with this thing and it has developed more issues.
Now once it starts it clearly isn't hitting on all cylinders.
It idles at about 750 rpm's then it starts to spit and...

Ya, I was thinking more on this today, and I think I am going to check the timing and see what it shows, and go from there.

I have had this motor for 5 years and has always ran very good, no issues at all. Put it up for the winter and right out of the box it has developed an idle issue while in the water. It will idle all...
