Motor Help?
Went to a Yamaha dealer today to look at a used 2001 Yamaha 150 HPDI 25". There asking $6,000. Motor has very low hrs, guy bought a leftover boat & motor then decided he wanted a 200 hp. With my 89 Yamaha 115 hp top speed is about 26mph at 5300 rpm. I'm thinking i should top out in the mid thirities at lower rpms using less gas with the new motor. Not sure the HPDI is a good thing I know they had some problems with the 200 & 250 HPDI models. My boatyard (old school) mechanic likes carb. motors, says all these motors with their electronics and salt water don't mix? Is the Yamaha saltwater series the same? I was really trying to hold off till the new E-Tecs came out ,they have so much to offer. Crusher

Re: Motor Help?
I honestly cannot speak from experience. But, while all the new technology is very interesting and tempting, I tend to side with the old school mechanic. Probably because I've been brow beaten by a similar mechanic that feels the same way. It does seem that when something new comes out, it's all very exciting and rosey for a while, then the problems begin. Carb'd motors have been around for a long time with few problems and I like that warm fuzzy feeling I get from long proven technology. I'm sure someone here can give you better feedback on some of the newer motors than I can.
Mine is an '88 (I was told '89 by the previous owner but from everything that I can tell, I believe it to be an '88) Yammi 150 (carb of course) and it pushes mine to just about 38 mph. I think a 150 hp and above is perfect for these boats because the motors are not working as hard. Motor load plays a big part in the longevity of your motor.

Re: Motor Help?
Thanks for the replies. I don't mind new technoligy the carb & DI modles seem to be trouble free. I posted on another board and got a couple reports of problems. Seems there is a lot of trouble with the 200 & 250 HPDI. models? I think I'll wait and take a look the new E-Tec. In a couple weeks I'm going to redo my Bimini enclosure, maybe next year , new 175 E-Tec,trim tabs, electronics. I need to go fishing to get over this money spending dream? Crusher
