Dang, talk about you got to pay-to-play. Makes me want to mount oarlocks all around my boat. If you want to fish with me you got to grab an oar. ;-)

another thing to know regarding any of the newer style engines(2 stroke and 4 stroke) is that the manufactures are not treating fuel issues under warranty, any trash or water, and clogged injectors, fuel pumps that are stuck up, all related to bad fuel and or sitting up without proper treatment, all not covered. Opti injectors are around $300, it takes 12 for a V6, 6 fuel, and 6 air(yes, they go bad also), they can be cleaned for around $80 each. Fuel pressure regulators on the fuel rail are not servaceable, they include the fuel rail(around $1300). The platinum plugs are $29 each, plus you can put over $100 of filters(air and fuel) at your next tune up. Now throw HPDI's in the ring, high pressure fuel pumps are over $1000, I can't find any one to clean(and guarantee) HPDI injectors, Injectors are over $300 each(only 6 to mess with). Electric fuel pumps are over $600(fourstroke also), the high pressure fuel filter was over $300, dealers complained about it so much they dropped the price to around $120(?, I haven't had to replace one lately), still pretty high. Add in DFI oil($35-$45a gal), adn ring free or carbon guard(highly recomended) at $20 per 100 gal. These things get real expensive,real quick. They can save you a lot on fuel, but they will eat you alive on other issues. I looked at a 115 Yamaha 4 stroke the other day, it wouldn't shut off, you could unplug the harness and it would keep running, you could lightly tap the computer and it would shut off, guess what, $1300 for the computer. lately, teh most expensive things I've been seeing is trim systems, just worked on a Johnzuki, had over $850 in parts on the trim system( '03 140 fourstroke), put a trim motor on a 225 yamaha, $580 for the motor. Makes me like the old 2 strokes better and better, Of course, these new motors are what keeps me in business

I've had a lot of good luck with Flagship marine for cleaning injectors. They are recommended by Yamaha and will do HPDI injectors. They provide you with a flow reading before and after cleaning of each injector. Also the Opti uses an iridium plug that is a little more reasonably priced than the platinum. But as long as you use good gas and dfi oil you shouldn't have to change the plugs every year.

Those were the early model Opti's, the newer ones are supposed to be even better. I think 3500 to 4000 is the sweet spot on MPG. Sorry for the passing of a fishin buddy, that sucks. I wonder what repairs he had to make, 2000 hours is a lot.



Like I mentioned, he maintained those motors well during the time he had them...the only repair I recall was on one of them an internal seal failed and allowed water into the motor...he realized it right away and had the seal replaced...no problems after that..

Spare...that was Nick, the guy with me the day I came by the docks and picked up the trim tabs I got from you...he's on the left in this pic I took in better days out in the Stream aboard Phat Kat...
