Yes that is the corrosion issue that i also experienced. I had to replace exhaust & other parts for both engines last year. I would suggest dropping a note to boat us, they are collecting data on this corrosion issue, the guy i emailed CFort@BOATUS.com GOOD LUCK

I tilted one engine out and with the tabs all the way down i did plane on 1 engine (F225). The issue as that the wide open rpm was 4500 rpm-not good. If i had lost an engine, i would run back off plane at 6-8 knots which is less strain on the running motor.

I cant quote exact numbers now but my fuel economy went from 1.5 - 1.6 statute mpg's 3 blade to 1.3 - 1.4 statute mpg's with the rev4's. Overall top rpm stayed with both props around 6k. Where are you located?

Thanks for the reply, how was the quality of the work?

I tried both 17m yamaha props & mer rev 4's 17". i found that my mid range speed did decrease a little & fuel economy across the board dropped a bit with the 4 blade mercs. I attributed that to the slighty smaller diameter of the mercs. The bite in the ocean was definately better with the 4...

Can anyone recommend a canvas place on long island ny that will redo the cockpit coming pads & the rear seat cushion? I had them redone 6 years ago & they are falling apart now-Any suggestions appreciated! Thanks

The fill plug is on tilt & trim assembly-i believe on the port side. tilt the engine up and fill until fluid reaches the plug. I had leakage around the trim cylinder seals, Do you see oil around these if so these should be replaced. not an expensive job and can be done by you,

Good luck to all. my Grady Charlie Tuna is suspended in the canal between both sides. Hoping that the surge is not as bad as predicted.

My f225's were installed in 2004 and never left long island waters. Always flushed after use so its not just a southern climate situation. As time passes, I think you will be hearing more on this issue. I did not have overheat warning but had to pull a powerhead for replacement- i had corrosion...

gman, Drop an email to Boat US, They are compiling data on exhaust corrosion and will present it to Yamaha. I know what you are going through since my 2004 f225's had the corrosion issue earlier this year. We have to get together on this issue for yamaha to take notice & hopefully stand behind...

Boat US has been very responsive with me. I sent all the information on my repairs. Lets hope Yamaha makes good on these unforseen repairs we had to make on our just out of warranty expensive pieces of aluminum that powers our favorate boat!

I inquired with grady white on this issue, the port side appears to be reasonable accessable by removing the bait well, the starboard side is the tough one. The suggestion was to cut an access port behind the transom door to access this area, I have not tackled this job yet!!

Since i had problems with the corrosion this year, I contacted boat us via email. They are compiling data to be presented to yamaha. I would suggest if any others had a problem to send them an email like i did the email is consumerprotection@boatus.com

i would think that would be a good starting point. remember the 4 stroke has to be propped to wot-6000 rpms. What rpms is your 95 sws 250 turn now?

oh by the way, this access the engine oil drain plug not the lower unit drains which are 2 regular screws on the lower unit

there is 3 or 4 allen wrench screws, they are easily visable. the one in the back of the cover has a metal slide in threaded piece, be careful not to lose. remove all screws and the cover pops off

is the wide open rpm within yamaha specs.

i had a similar problem with my f225, it turned out to be a low pressure fuel pump. There is a fuse under the motor cover, i would see if that is blown. If it is i would replace and listen to see when the key is turned on (not started) you will hear the pump run. If the low pressure pump is bad...

I have a 98 sailfish but i do not know the name brand of my butane stove. I see you are a long islander like me & i get the canisters from jetmore in wantagh. the cans are $3.99 each. I use the stove often in the cooler months. Nothin better than hot soup in late november blackfishing!!

Yamaha also let me down with my 2004 f225. one block (570 hrs) had a corrosion hole from inside out just behind the thermostat. i flush every time & change all the zincs/anodes. The warranty ended 1.5 years ago. they gave me a token $500 for a new powerhead. I also had to replace the corroded...
