Buying a new Yamaha outboard??

[catdogcat]

I'm planning on getting a new 75hp Yamaha 4stroke this weekend. There offering a new old stock 2003 for 6900 with install and accessories. Seems like a good $$. What do you guys think about the new 05. Is it worth the extra 1000.00 for the EFI. I hate carbs but really like the discounted price. The extra 1000.00 will definately be hard to come up with.

Can't answer your question, but about 3 weeks ago we bought a 2005 F8 from River and Sea Marine in Soldotna....great people and great price. If you haven't called them give 'em a try. We just love that motor. Very quiet and we can troll 5 hours on less than a gallon of gas!

Thats who I've been dealing with. You got lucky with them. Their jerks, some of the most rudest folks I've ever delt with. If they didn't have such a good price I would avoid them at all costs. Went in there today and they made me wait about an hour only to tell me to come back this weekend, lady was very rude. I must have been disturbing her lunch hour. I could tell you a number of horror stories but I won't go into that. They do sell nice motors though. By the way nice pics in your album. Love the octopus.

Geeze, sorry you haven't had the nice experience we had. Of course we did it over the phone, and they NAC'd the motor over here within a few days. Beat the local shop by 110 bucks...and that included delivery! It was one model year newer, to boot. I wish you luck.

Glad you liked the octopus...our "record" if you can call it that, is 3 in one day. I hate the dang things, they're so hard to pull off the bottom when they get into their holes. They do make great 'but bait, though! Stay on a hook all day long...

catdogcat-

I have the new EFI 2005 F-90 and haven't had a single misfire or failure to start immediately yet. I paid $8056 out the door here in California. The motor is flawless, but not having had a carbed four stroke before to compare it to, can't really say if it's worth the difference. The EFI probably will get better gas mileage than the carbed engine, which would eventually help offset the cost difference.

This brings up a major point of concern I have here on the discussion board. We often are trying to make comparisons and or evaluate options but each person has only had a limited exposure to their own equipment. Pretty hard to compare apples to oranges to pineapples when you've only tasted one of them! But we do the best we can, and every once in a while we get someone who's tried them all like Dusty!!!

What is the break in period like?

[Sneaks]

I have the 2005 F75 so can't compare it to the non-EFI. Same experience as Joe's F90. Break in goes in steps for the first 10 hours. All I remember is the boat actually planed even at the lowest step and after the first 2 hours you're not gonna hold any of the Grey Beards up by much.

I deliberately waited for the EFI.

As I remember*, you have to run the engine at specified rpm for the first two hours, then you're limited to a certain rpm for several more, and then you can open it up providing you don't run it above 5000 for more than a few minutes at a time. The first check up with the dealer is at 10 hours. The EFI engine has a computer that records all the rpm range usage and self-diagnoses any problems, but only the dealer has the read out computer.

*The owner's Manual is in the boat at the lake.

One other thing...They've managed to quiet down the 2005 model quite a bit with the EFI. In fact, it makes less noise at idle than my Honda EU1000i generator does when it idles !!! Have to look at the tach to see if it's running from inside the cabin as you can't usually hear it! Joe.

As a former auto mechanic I have mixed feelings about EFI on boats. Here is why. With a carb it is fairly easy to remove them and clean the jets when they get plugged. With EFI your ONLY recourse is to replace expensive injectors. Since we don't use our boats every day or even every weekend the fuel systems are very prone to problems of gumming up (I usually have to clean the carb on my kicker every 2nd or 3rd time out). However, I also think that the EFI system is less likely to plug up. The high pressure of the fuel system will often promote self cleaning of the injectors.

So, having said that I also like a lot of what EFI gives you. IE: no worries about a choke, altitude changes, get better fuel mileage, etc. IMHO If you do get the EFI you have to be very careful to use the fuel stabilizers. Not doing so could be a very expensive lesson. Since I'm not too good about doing that I prefer to go with a carb that I can fix myself.

I've gotten so that I can R & R & clean the carb on my Honda 7.5 in about 20 minutes. Since the gasket is usually just fine on the float bowl I don't even have to replace any parts. Just blow out the idle circuit and put it back together.

Let me say that I DON'T have an EFI outboard to give you an idea of how prevailent injector problems are. For that I would call and talk to some boat mechanics and ask. It might also be interesting to find out how EFI on Harley's have worked since they often sit a lot similar to boats. I do know that Harley won't be offering a carb on any of their big twins next year.

I was thinking about a pair of 75 HP Yamaha 4 strokes as a repower for my boat. http://www.marine-movers.com/Rosborough_22.html
However it appears I am learning that the EFI is only available as of this year, and I thought EFI had been on Yamahas for a few years.
I haven't heard of any complaints about EFI's being particularly sensitive to fuel issues, but has anyone else?
All the manufacturers seem to be going to EFI, so I think it may be the only thing available pretty soon. seems like most folks think EFI is the way to go.
Any comments on these engines and EFI will be appreciated.

Thanks, Gary, for the comments.

I use Ring Free/Techdron and Stabil in each tank of fuel I put through the new engine. I also use Sea Foam at each 10 hour interval, but just added to the tank gas, not dumped into the manifold. Time will tell! Joe.

I have a 2003 yamaha 4 stroke w/carbs on my 2004 c-22 and had no problems....great engine/gas milage.....very quit also!! So far Iam very stoked w/powerplant and boat!! Sure beats my father in-laws 24 ft skipjack with a volvo penta v8 ..it cost him over 250 bucks to goto catlina for a fricken day... dock gas bites...trailerboats ROCK!!

Larry, Yamaha has had EFI on larger engines for years. 05 is the first year for EFI on the 90 H.P and smaller engines. I think I read on the Red Fox website "Sound Dreams" that he has never used any fuel additive in his Yamaha 115H.P. and has never had any problems. He runs in the cool Alaska weather. Link to his site in on the main page.

CatdogCat..... I went the extra $$$ for EFI on my 2005 Yamaha 90 and am more then satisfied. Just wanted to get away from carb's. Although we use the boat year round down here so gumming up the carb is not an issue, nevertheless, I've never found it to be an issue with EFI. My bike has EFI and when I was in hospital last year I didn't use it for 4 months, but when I got around to starting it, it started right up.

My friend, a snow bird, has a 90HP Yama with carbs, and every spring when he heads back up north, he does all the necessary, stabil in gas, etc, but every fall when he returns, the motor won't start and in the shop it goes to clear the carb's!

I guess if you use it year round, no problem, but if you store it that opens the door for problems. Years ago they use to have a drain in the carb and if you ran the engine dry and then drained the carb you generally didn't have a problem, but most larger engines no longer have a drain screw in the carb........... Don't suppose this helps, just adds to your uncertainity.
