checked vacuum after rebuilding topend

[bighvygsx]

redid topend and didnt touch bottom. my guy says it should hold 5 psi for like ten minutes. mine holds 5 psi for like 2 min. what does this mean? what happens if i run or break it in thisway. is there anyway to swell the seals?

You need to add you model and year to your avatar so we know what seadoo you are talking about. Also, it's not the vacuum that counts, but the compression. If your mechanic says you need to swell your seals...get a new mechanic. He hasn't got a clue.
