Purchased a 90 SN yesterday and decided to do a build. Had a 701 62T but I'm thinking Jetmaniac 718 or BB. Still thinking on that one. This is my first SN, so any suggestions are much appreciated.

Congrats! You really cannot go wrong with any of these engines.... 62t 701 properly set up can/will run well.
What is your experience and goals? Are you a newbe? Racer? Surf Rider? Chase boat waves / jump?
One thing I would strongly suggest - strip the ski completely, go through th driveline, mid shaft, etc. Rebuild with new quality bearings, and seals. I would drill small holes at the back of the hull and check for water in the tray/foam area. Remove all wet foam and re-do if needed. MAKE SURE to seal up the hull at all the known leak points, where the cables, exhaust ,and drive tube go through the hull.
Done right, and you will have a good solid ski that will give you years of fun.
The thing with these old SN's is they hold onto a lot of water under the tray in the foam. Not uncommon to remove 30-40lbs of wet foam. Other then that I would add a 9/15 hooker impeller and a bpipe.
-The more power, the better.
-Round Nose handlepole that I could cut to fit me was a major improvement. Don't even need a new pole bracket if you can work a cut off wheel for 1.5 minutes.

No idea sorry. I cut from the bottem on the RN pole where it inserts into the metal bracket.It has an aluminum pole. Are those able to be shortened? If so where did you cut yours? Bottom or top?
