    Will 1050 cylinders fit a 700?

    I am trying to figure out if its worth rebuilding a 700 SLTH I have, and was wondering if the 1050 cylinders were the same as the 700 cylinders, since they are 350cc either way. Also where can I get them bored if I decide to just rebuild the ones I have.. preferably in florida since shipping would be better.

    One other thing, are there other parts that will swap over? like on a 96-97 700?? I know I'm asking a lot but maybe someone has done this before..

    I'm not an expert,by far.Check your cyl# at parts.partsland.com advanced search.I think that's the correct address,if not may be someone will correct me. I beleive 96/97 700-98/99 1050-2000/01 700 are same.96/97 1050-98/99 700 are same.Main difference will be fuel mixture/jetting,but always a good idea to check mixture with any engine work.Best to find same # cyl you have.If not replace as pair.Hope that helps.

    I have the following one digit part number differences.

    #3021017 - 99 Genesis, 99 SLTX-B, 99 Pro 1200, 00 SLX, others.

    #3021018 - SLTH, SLH, others? doesnt show before 98

    #3021019 - 99 SLX, 98 SLTX, 01 SLH, 01 Virage, others.

    Are these three interchangeable.. IE different bore sizes only, or are these all different parts alltogether. They look the same on the parts manual. I know with a lot of parts they have different part numbers but are interchangeable.

    joyrider,sorry for the delay. The 017 is definetly a larger bore,84mm,for the 1200.I really don't know if it will work,somebody mentioned the 1200 has a longer stroke,I don't know. As far as the other 2,both are 81mm,either will work.I was told they have different port timing,minor port location difference. Which causes 1 to need more fuel than the other.The 3021018 (more fuel) replaces 3021009 were the 96/97 1050,are refered to in the parts list as "HP". 3021019 replaces 5131081 were the 98/99 1050 96/97 700,refered to in parts list as "KONIG".I don't know if there is a performance difference.As always,check your plugs/piston wash as soon as you get it running,don't run it lean,will cause engine damage.

    Any of the 81mm bore cylinders will fit your 700. Ideally, you would run two cylinders of the same part number. Some of those cylinders had drastically different porting, which changed the running RPM and jetting. There were three 81mm cylinders, 009, 018, and 019. The 009s subbed to 018 I believe.

    Post a want to buy in the classifieds and let them come to you (cylinders). As far as pistons go...I prefer the OEM Polaris ones, but they are $130 ea! If it's just a recreational boat, I'd go cheap and buy the WSM platinums. There are some running those in modded motors with good results.
