Default 115 Optimax question

I have a 2006, 18' deep Vee with a 2006, 115 Optimax. I fish freshwater only.
Question; On the third trip to the lake after unwinterizing the engine, I was just crusing along at 38 MPH.( wide open 43 MPH), and the engine just shut off. I pulled the trhottle back in Neu. and restarted without any hesisation. This happened 3 times till i got back to the ramp. I went to the local boat shop in my town and was told " Thats just the way the Optimax's are". I was not sastified with that answer, I came home pulled all the plugs out, cleaned with carb cleaner and wire brush, rechecked the gap and reinstalled the plugs. This past Sat 4/19/08. I went back up to the lake, and the boat didn't shut off but I couldn't get it over 37 MPH.
Any advice would be helpfull, I do not want to take it to the shop that makes stupid comments like that.
Thanks

I'm not overly familure witht the optimax... but NO engine should shut down in the middle of a run.... ther answer you recieved is irresponsible and unacceptable...

First toss the plugs for new ones, they are cheap enough and should be replaced after the winteizing oil is burned off....

How the cooling system..... most outboards have a control that limits the RPMs or shuts down the motor if they get hot..... the same applies to the oil injection system... all controled electronicly with sensors, so even if there is not a malfuntion, they still could cause a problem...

seeing the engine started up imediatly I'm ruling out water in the fuel( or until Ihave more info) or a bad check valve in the primer ball... if you have a water seperating filter change it and check the contents.... water in fuel related problems are the #1 headache of boaters, especialy in the day of reformulated and alcohol based fuels...

Thanks for the quick reply Roc.
Thats how the whole thing at the dealer got started. I was going to buy new plugs, they said the cost was $20.75 EACH. So I said "before I spend that much money on plugs, this is what it's doing" then I got that stupid answer.(sry, but that answer still has me steamin')
While running last weekend I watched the water shooting out the engine full stream while the wife drove the boat. I do not have a water seperator, the boat didn't come with one. I will look into putting one in, any suggestions on a good brand?
I will also find another place to purchase my plugs.

$20 spark plugs doesn't sound right at all.

Take it out and go down to the auto supply store. I'd say they're more
like $3.50 each...

I want to thank all of you for the feedback, I did go to NAPPA, and paid $14.50 each. The ones in the web site from Rick are the wrong ones for my boat, I have the 115 Optimax DFI 3 cly. plug # IZFR5J.
After i put the new plugs in on Thurs. I had a Striper Tourney over the weekend. I managed to catch 2 fish, even with the bad storm that rolled thru Sat eve. to Sun Morn.(weather channel on radio said 60 MPH winds and Hail mixed with rain, THEY WERE RIGHT) The boat ran ok but still not up to par. I was only able to get 40 MPH out of her. thats still about 3 to 4 MPH slower than before it shut off those 3 times. I heard the alarm go off only 1 time, I throttled back and the alarm went off, then throttled back into her again and no alarm. I am going to take her to the shop and let them connect to the onboard computer, something still aint right. I will post the findings after I get her back.
Also thanks again Rick, for the NGK web site. I will be ordering my plugs direct from now on.

Just An update;
I took the boat to another shop, Bowers Marine, in Hagerstown Md. i took the boat there in May,2008. they told me that my problem was that rings collapsed in the cylinders. They are supposed to read 120psi per cyl. and mine had a reading of 87psi. I STILL to this date have not gotten my boat back yet, I called mercury marine warranty service, they told me that there was nothing they can do it is up to the repair shop. I asked that since the motor is a 2006 and I have a 5 yr. warranty, why don,t they just unbolt it and replace it with a new motor, they said " it is not our policy to replace the motor since it was in service for two yrs." I asked then what is the purpose of having a warranty if you are not gonna back it up. I also told the woman on the phone that when I finaly do get my boat back, I am going to tow it to an Evenrude dealer and ask how much they will give me for that peice of crap, and put an Evenrude E-Tec on the boat. I dont think I will ever buy a Mercury engine again, and thats sad because I trade my boat in for a new one every 5 yrs. their loss I guess.

May I ask what prompted the change of heart?

sure, Come to find out that not only was I pissed at Bowers Marine, but so was Mercury Warranty Svs., The new powerhead has been in their shop for a while, and they just keep putting it off, so it wasn't Mercury that was the problem.

But I was dead serious about switching to a E-Tec, so I did a lil research and look at what I found;

There are many tests out there on all sorts of engines and when posted they are invariably shot full of holes in that "the props are not the same", "the boats are gassed different", blah, blah blah..FROM THE EPA and bench tested - no boat involved:

Per 2005 EPA Certification Data:

250 Verado - 656 NM (482 ft-lbs) at 4000 RPM through a 1.85:1 gear ratio = 892 ft-lbs max at the prop shaft at 4000 RPM
250 E-TEC - 575 NM (423 ft-lbs) at 3091 RPM through a 1.85:1 gear ratio = 782 ft-lbs max at the prop shaft at 3091 RPM
250 Suzuki - 313 NM (230 ft-lbs) at 4500 RPM through a 2.29:1 gear ratio = 526 ft-lbs max at the prop shaft at 4500 RPM
250 Yamaha - 303 NM (223 ft-lbs) at 4000 RPM through a 2.00:1 gear ratio = 446 ft-lbs max at the prop shaft at 4000 RPM

225 Verado - 635 NM (468 ft-lbs) at 3500 RPM through a 1.85:1 gear ratio = 865 ft-lbs max at the prop shaft at 3500 RPM
225 E-TEC - 518 NM (381 ft-lbs) at 3091 RPM through a 1.85:1 gear ratio = 706 ft-lbs max at the prop shaft at 3091 RPM
225 Suzuki - 312 NM (230 ft-lbs) at 3500 RPM through a 2.29:1 gear rato = 526 ft-lbs max at the prop shaft at 3500 RPM
225 Honda - 295 NM (217 ft-lbs) at 4000 RPM through a 1.86:1 gear ratio = 403 ft-lbs max at the prop shaft at 4000 RPM
225 Yamaha - 294 NM (217 ft-lbs) at 4500 RPM through a 2.00:1 gear ratio - 434 ft-lbs max at the prop shaft at 4500 RPM

the Verado just blows the E-Tec away by OVER 100 ft-lbs,
The Verado numbers helped me decide what I wanted. Man that thing just launches my boat to 37 MPH outta the hole. LOVE IT
Jim

Yes it is yung money. Now that I am past the break in period, When I open her up at 6250 RPMs, she'll run between 53-55 MPH , My cruising speed is around 4000 RPMs, which is between 40-42 MPH, handles like a dream,even in some rough chop. I am still amazed at how quiet this Verado is. Sometimes I catch myself wanting to start it with the engine running , I got in the habit of looking at the tac. B4 starting.
