bronzebackhuntr Posted February 16, 2013 Report Share Posted February 16, 2013 Ok, finally got the boat picked up and home. Here is where my questions start. I have never had a jack plate, they put me on an 8" Pro-Hi-Jacker. Where do I even begin when I take this thing out to start adjusting? Link to comment Share on other sites More sharing options...

BulletDeuce Posted February 16, 2013 Report Share Posted February 16, 2013 Chris, congrats on the new motor & jackplate. My dad had over 700+ hours on his 150 Mercury the same year as yours without any issues or rebuilds. They are strong motors & should last you as long as you own the boat. Also, make sure you use 93 Octane as those motors do not like the lower grade. Now, to the jackplate. Based on my experience with Skeeters I think they like to run buried in the water, it looks like from your picture you need to drop the motor down to where the plates line up. I would start where its at as baseline & work my way down on the jack plate. Link to comment Share on other sites More sharing options...
bronzebackhuntr Posted February 16, 2013 Author Report Share Posted February 16, 2013 Thanks Wes. That's the plan is to start where it is and go from there. Next question with your gas comment. The morning that my old motor went out I put $40 of regular in it. Do ya think I should add some octane boost or some seafoam or something in it for this first run?

I would throw some Octane boost in there if it were me. IMHO the 2.5 Liter block on those motors is virtually bullet proof, and pretty easy to work on. The Triton that I posted in the Classifieds was run on 87 & eventually blew up twice. I would rather spend a few dollars more at the pump, than a few thousand getting everything rebuilt every few years. Link to comment Share on other sites More sharing options...
basslover79 Posted February 16, 2013 Report Share Posted February 16, 2013 I would run it and see how it runs the way they put it on. Then, I would mark the plate in 1" increments and drop it one at a time until I found the sweet spot. If it blows out when you start planing down then drop it again. I still need to adjust mine down just have not done it yet.. Link to comment Share on other sites More sharing options...
Mountainman Posted February 16, 2013 Report Share Posted February 16, 2013 +1 on the jack plate stuff....only Id drop/raise it half or quarter inch increments. I know a 1/4" makes a big difference on my Phoenix. My advice to you is to take some tools o the ramp and leave the rods at home. Run it, pull it out and tinker with the JP, then run it again. Repeat til you find the optimal height. Keep an eye on RPMs and kknow where your motors high, low and optimal range is (keep in mind that this can also be altered thru prop changes) AND water pressure. The higher you go on the JP, the less water goes in the water pick ups. Link to comment Share on other sites More sharing options...
softbaitmaker Posted February 17, 2013 Report Share Posted February 17, 2013 Glad you got your boat back home. Can't help on the jack plate issue. Every time I need something done regarding jack plate work I just call my buddy BT and he fixes the issue but since my Bug Boat does not have a jack plate on it BT helped me with prop work and boat has run great since he fixed it in 1998 when I got it. Good luck getting yours set up and I would run High Test if the motor book called for it. I began running High Test when I first got my 98 with the 130 Yamaha on it and ran it for a couple years. I got to talk with a Yamaha Rep at a show in 2001 and he told me that I should be running 87 in it. I asked him why and he said that the on-board computer on the motor was set up for 87 and I would see no difference in mileage or performance. I ran the fuel out that was in it and put 87 in it. To my surprise I didn't see in difference in performance or fuel mileage. I have been running 87 and about every third tank I will put a tank of mid-grade in but still see no difference. I have no knowledge in Mercury's since I have not owned one since 1989. Been Yamaha ever since. Good luck with your Bug Boat. I know I love mine.......

blind hawg Posted February 18, 2013 Report Share Posted February 18, 2013 You may want to do some research but i've heard that high octane fuel will break down faster than low grade fuel thus causing issues with ur fuel system . The yamaha I had before this one said to use 87 only and watsons said to use 87 in my 200 hpdi. Link to comment Share on other sites More sharing options...
BulletDeuce Posted February 18, 2013 Report Share Posted February 18, 2013 Chris-give Craig France a call @ Watsons, he's gonna give you the same advice as I listed above. Also, a keep in mind that lower Octane gas burns hotter than Higher Octane gas. Lower Octane will also cause more dramatic Carbon build up on the rings & head.

I believe that this is not correct...... The colder it burns the more carbon in made..... At least that is what I was told by a master mercury mechanic when I asked about running 93 in my Optimax. Some motors require 91-93 and others (like the Optimax) are programmed to use 87. The owners manual will tell you what to use and higher octane is not always better.

MOONlite Posted February 19, 2013 Report Share Posted February 19, 2013 most 2.5 merc engine failures are from melted pistons. this is caused by some form of pre-ignition from too low octane, too much prop, defective timing modules, lean fuel, etc. check compression or leakdown if possible to be sure your cylinders are in good condition. remove all idle stabilizer/anti-knock boxes and set timing from 20 to 22 degrees. prop the boat so it can turn 6000rpm with proper trim in fully loaded condition with all equipment, people, full livewells, etc. keep fuel level low so that gas stays fresh. use carbon cleaner such as seafoam in every 2 or 3 tanks. if you have a lab to test for octane and you can be sure you're getting 87, it should be ok if all other conditions are correct. i don't trust octane ratings. i tested some gas out of a boat with a melted piston. i tried it in my lawn mower and an old car. it would barely run in either. i think it had kerosene or diesel mixed with it which really lowered the octane. you can smell the difference in 93 and 87 octane. the newer optimax with lower compression should be safe with 87 but i have seen melted pistons in a couple of those. i've run nothing but v6 mercs for 30 years and have used nothing but 93 octane. i've never melted a piston. every stock fishing type engine i've seen with melted pistons were using 87. it's your baby so run what you think, but i want every possible safeguard against detonation i can get in my old naturally aspirated 2 stroke mercs.

Now you hear it from the man himself, thanks for sharing. I have always been told the same & like you said. If you got $$$ every few years to re-build a motor, then keep running the 87.
