Finally got the "new" toy out for a test run yesterday. Managed to clock an indicated 6500 RPM at WOT (in the short length of "flat" water I could find that would allow a long enough look at the instruments without stuffing it or going airbourne!
Now, the only reference I can find to my generic Yamriner 2 cyl 2 stroke is on a scan of a Mariner 55 "Marathon" Microfiche. It says I should have topped out at around 5500.
So, Does anyone know if the marathon was purposefully "maxed" at 5.5K, or better still does anyone have access to paperwork that might tell me what my theoretical max should have been. ('79 vintage Yam 55 2cyl 2 stroke) It was literally screaming when it happened, and sounded "normally WOT" when throttled back to 5500, so I think I may have too low a pitch on there! Mind you, 2 - stroke Yams are always rev - lovers, so maybe 6.5K isn't that unrealistic?
Apart from that it was a good trip, only other big problem was my knee against the fast idle lever. This weeks job is going to involve moving the remotes up the side of the console by about 6".........
