    90hp Nissian won't open up

    Update, took to mechanic today and before I left town a few hours later he called and said it was in better shape. Whoever deleted the oil injection left some things not plug so big vacuum leak, also it wasn't in time on low in or high end. And main issue is it has an 18 or 19 pitch prop and...

    90hp Nissian won't open up

    I pulled carbs off again this morning, took them all apart, carb cleaner and blew air all the way through, put it back together, had another set of plugs, put them in and ran it a little while ago. No change. Taking it to a mechanic this evening. Will update everyone when I know something...

    We have had this boat a few months and previous owner said it was running fine, we swap trailers, ran all new trolling motor wiring and new turf on all the decks, new trolling motor, new paint on boat, it has been a project. I'm thinking about pulling carbs back off and checking to see if they...

    90hp Nissian won't open up

    It's a 2000, it's in original post. I think it's an NS90A. 10-4 on over night soak. I though I got them cleaned out good, but maybe not. Thinking about taking it to boat guy. Hate I can't fix it.

    90hp Nissian won't open up

    Thanks dwco I just had carbs off and cleaned them out, but that could be the problem. Fuel line is pretty straight even when tilted up. Now I do not know how old fuel lines are. Probably wouldn't hurt to replace them.

    90hp Nissian won't open up

    I don't think the prop is slipping cause the rpm's aren't going sky high, rpms are really low at wide open throttle and the boat isn't really loaded down. Seems to me it is a fuel problem, especially if it seems to help when I push the choke in really fast. When I took carbs off and bowls off...

    Thanks for the reply Sea Rider. Yes sir 2 stroke, fresh water, it has a stainless steel prop but it doesn't seem to have any slippage, not sure of pitch.

    90hp Nissian won't open up

    2000 model 90 hp Nissian just got boat water ready and motor runs fine on muffs. Took it out Sunday and on the 20 foot sea ark the motor won't run wide open. Throttle all the way forward and it runs 12 mph. Brought boat home, took carbs off and apart and cleaned them good and ran boat today...
