Thanks Don for the information and explanation. I was just trying to understand exactly what was happening with the trim sensor.
Best,
Kenny

I think you will spend around $50 for the trim converter 8M0059529 or you can opt for the 2" SC1000 digital trim gauge 79-8M0052849 as MichaelJ3 mentioned, simply plug in the link cable, and have the...

For those who are doing similar installs, the Mercury vessel harness 84-M0079545 works properly when connected to the Merc-monitor 8M0079866 / 8M0100795, Merc/Airmar Triducer 79-8M0075628, and to the...

Sorry Don,

As I'm new and always seem to be doing the wrong things on this site lately, just reading through the sticky notes and completely understand your position on E-bay purchase questions -...

Hi Don and others.

After an exhaustive search, I found a new (and seemingly rare these days!) Mercury 150 XL 4S (2B582043) at a very good price from Central Georgia Marina. I sold my 2000...

Many Thanks. I'll post on the other forum.

Many Thanks to all for the advice.
The cheapskate devil on my shoulder keeps telling me the wrong things to do.:doh:
I think by the time I invest the money needed to get this motor back to a...

I have a brand new water pump on my 135. Anything wrong with swapping the foot just for the purpose of supplying water and starting the 150?

Would it it hurt to spray fogging oil into each cylinder and rotate some turns or would a little of the DFI oil be better?

Not to bore with details, but European Marine recently checked my 2000 Optimax 135 and it had low compression on cylinder #1 (among many other problems) and isn't worth repair - Many Thanks all their...

Perfect!

Many Thanks Don!

I recently installed a Mercmonitor on my 90 ELPT 4S L4NA S/N 2B074374. I already had a water pressure gauge on the console and want to keep it for redundancy if no issues:

1. Can I simply tee...

Thanks Don for the reply and confirmation!

I hope you will be able to inspect this motor soon for the problems described in the Mercury Motor forum - I'm currently on your waiting list.

Best,...

Hello,

I have a 1999 Optimax 135 S/N OT146641. I just installed a new mercmonitor gauge on a 4S 90 HP, I like it a lot, and thinking about the same for my Optimax 135. From everything I've been...

Many Thanks for the comments - understand a little better now.

Thanks Joe.

I live in Anderson, SC, which is only 30 minutes away from Greenville. I'm going to take her to Don for a complete inspection.

Hello,

Just wondering the primary reasons Mercury made the latest design changes on their 90 HP 4S engines? I have a 2013 Mercury 90 ELPT 4S L4NA S/N 2B074374. From what I gather, this motor was...

So my old VOM was off. Here's better numbers using a newer VOM + Ammeter:

*Battery voltage not connected to motor: 12.6 VDC
*Battery voltage connected but motor not running: 12.6 VDC
*Alt. Large...

Thanks Joe.
Im using an ancient Fuke digital meter and wondering if it could be off calibration, which could explain the higher volts I’m reading. I’ll recheck with a newer meter to verify.
Thanks...

Thanks to all for feedback. I have a plastic fuel tank so not sure about cutting to install a “normal” level sensor.
Sorry I posted in wrong place. Ill be sure to post in 4S forum next time.
Many...

So I checked the alternator and heres what I found:
*Battery voltage not connected to motor: 13.6 VDC
*Battery voltage connected but motor not running: 13.6 VDC
*Alt. Large red lug with motor...

Seems I read the same and assume I could just reset after refilling the tank. I have a spare hole on my dash that I wanted to fill with a SC Link fuel level gauge, but certainly will try the...

Over mine too Joe, that's why I'm asking others but don't think there's much out there right now. My bet though is there will be as wireless stuff is taking over.

I did find an interesting article...

I have a 2013 Mercury 90 ELPT 4S L4NA S/N 2B074374. I am installing a mercmonitor gauge soon and would like to read fuel level in my tank. Unfortunately, my tank is an above deck 24 gallon Moeller...
