    question on the 135hp 1200 motor.

    Guys I am looking for a boat for the youngters. I am not giving up on my doo's, but it is time to look for something that will carry the little ones.

    I have owned a exicter 270 RED/White. I loved that boat, but it has been awhile since I have had it. So I can't remeber to much about it.

    My question is I am looking at a LS2000 with the twin 1200 135hp motors. Just like my old exciter.

    Well this boat is a deal. mint shape $8000, but it was kept in the water.

    Does the yamaha motors suffer from the bad engine rust like the seadoo 2strokes? It has sat in the boat slip for 3 years and always taken out for winter except for this year. It sat in the water this whole year. So please let me know how this motor reacts to this? Does it get all rusted up in the crank like the seadoo's?

    Thanks.

    I don't know of any problems specifically involving rust on these motors. However, I would think that any motor that has been sitting for a while, especially while the hull is in the water could be likely to form some rust. If there is some water in the hull it would be in a moist enviroment and moisture would get in through the airbox. If the water box has water in it, moisture could get in that way as well. I don't think anything would be rusted so bad that the crank would seize. Any surface rust would likely go away after the motor gets hot and some oil runs through it.

    Yea, i really don't want to worry about the kids when they are swimming around the boat. It is really for us to go sit on the water somewhere and my oldest sons friend can bring the RXP's and RX and ride all day with the whole family.

    GPSLEEPER, I just am worried if the crank and journals get rust in them and then BOOM on a latter date.

    Anymore thoughts????

    Yamaha engines are marine-specific engines. Some of us (including me) have sunk our skis in salt water, run them the next day, and they're still going. I am of the opinion that Yamis are very durable engines. That's assuming proper care is taken, of course.

    This is great to hear.

    I will be able to run the heck out of it as he said he will take the day off, so I may run it and feel good about it. O mean heck it is on the lake in his slip.

    I will check comp. also and I thinink it should be in the 110 to 120ps.i. range per cylinder Warm?

    That is an easy fix, I plan on cleaning the carbs the day after I buy it. If I buy it.

    The Yamaha is not the same as the Do
    I have read the Do always stops at the same position (timing)
    So they are always open (port).
    It causes them to rust when left to sit something to do ith it being a 2 cylinder not a 3 cylinder.
