++2 :cool:
Very much appreciated :thumb up2: Great write up!
Any updates on the 2.5 water pump replacement tutorial? A few weeks away from doing mine, thanks for any update. I can only find the one for 1.5’s
Same here although it’s an 04 175 Optimax with IZFR5G gapped at @.032-.033 for 45hrs now after reading the FAQ. Mine runs great through all rpm ranges. Watching this as I’ll do plugs again in a few...
Ok, looks like I found it, Seems to work on most V6 Optimax digital outboards. #859187A1 Mercury Trim sender
Just searched on this forum to no avail, also searched the parts diagrams and sender doesnt look correct for my OT922039. Ground strap on lower unit looks good and when out on the water the...
Thanks Shuck, that makes sense. Will check all the simple stuff first.
Just took the boat out and had noticed this before, under load right before planning at 2900-3100 rpm it almost sounds like reeds slapping. Anyone else have this sound? Other than that boat ran...
Just got some 8ga and 14ga tinned marine wire from bestboatwire.com All were 25’ coils, 18.75 for 8ga and 5.00 for 14ga made in USA
Could use the old SC1000 monitor system, would fit where water pressure gauge is. It was used back around 2002 - 2006, I have one on mine and I’m always on water pressure or temp. It does RPM, fuel...
Bonus* with lower cowls off sprayed engine & cowls with engine cleaner, dried and coated with Yamashield I had laying around.
Thanks for all the help, now have new water pump, spark plugs, thermostats, Serpintine Belt, new strainer and new poppet kit done. Also replaced fuel line and primer bulb. Poppet was a little...
How about Gen 1 to gen 3 touch, want to upgrade
Might be a dumb question but here goes. I'm going to upgrade my HDS and wondered if my gen 1 HDS7 Navionics card will work for a gen3 HDS9. The one I'm looking at comes with no card and no mounting...
Thanks for the info! Found some kits on the <Edit-Announcements> and elsewhere but not sure if correct.
I’ll email Rhonda
Question for Don,
Searched posts her and elsewhere for poppet valve kits for my '04 175 Optimax #OT922039
Getting all the maint. done before next season. Thanks!
I’ve put about 12 hrs on my ‘04 175 in ocean conditions light to medium swells. After buying boat filled oil tank to 3/4 full and checked it yesterday and still half full. In those 12 hrs have gone...
I Will add the belt to list as well, Thanks Guys!
Thanks Silverfox and Don.
I was looking for impeller, gasket & housing KIT on Mercury parts but all split individually? Water pump and checking thermostats is on my list. I've done new strainer,...
Have some cooling issues after running 4-5 hours yesterday. Have a 04 Optimax 175hp serial# OT922039 on a Sea Pro 206CC. Heard a 2-3 beep alarm running off plan around 2200 rpm and saw 167degree in...
Got it! Thx
Would that same manual work for my #OT922039? Thx in advance
