Hello from Osan Korea,
I have a question for you guys. I am looking and thinking about upgrading boats from a 16 foot bow rider W/88 HP Evinrude SPL V-4 to a really nice both interior/exterior 1991 Chaparal 2000LS Bowrider 20 footer that has a 4.3 liter V-6 Yamaha inboard motor with the outdrive on the outside of the boat. My question is that it has plenty of battery juice and turns the engine over fast but will not run at all. The people that I am buying it from said that they have had it for 2 years now and only used it 3 or 4 times when they first bought the boat and last year they didn't even take it out becuase they decided that a boat is not for them and they are not boat people as they thought they were. So I am thinking the gas is probably pretty sour and no good at all and needs to drain all of it out of the gas tank and put fresh 87 octane and add Seafoam to he gas and spray Seafoam deep creep inthe aerosol can down the carb throat and let sit a little bit and try to crank it over with the fresh gas and Seafoam added to the tank and see if it runs for them. Is that good advice and what else would I do if that doesn't solve the problem. Thanks Bob

Does it have spark? Does it need a safety kill switch lanyard hooked up?

Like Don said, gotta see if its sparking. First, is it a EST model or YEMS? If it has the Yamaha ignition switch, it should have a clip behind the key attached to the safety lanyard. If not, then there should be a clip somewhere attached to a red lanyard. If you are unsure about diagnosing the problem, get a mechanic.

Heck Don, he's just around the corner from where they still build them. Or just across a bit of water.

Hello all,
Yes, I am at Osan Korea but will be comming back to the states on 8 March 2008 for good. I decided not to byt this baot so I am going to stay with my Chaparal 162XL Ski boat w/88 horse power SPL V-4 Evinrude it is a little small but it runs great, I redid the interior including the seats a few years ago and the great thing is its paid for and I can do the work on it myself if something goes wrong which so far so good, knock on wood, LOL. So I can't wait t get on the water with her when it gets warmed up. Thanks guys for talking me out of the Yamaha inboard/outboard Chaparal 2000LS 1991 model year. Take care, Bob
