[QUOTE="Skiffing, post: 385964, member: 15889"] I calibrated the tachometer and raised the engine other nine [9] threads - so, almost an inch. Now it's too high :roll: [img]https://i.imgur.com/iWczYMM.jpg[/img] We did 36 miles on the Merrimack River today on less than one tank. That includes numerous no wake zones and putting around looking for shad. On the down river run we opened it up. The tach hit 5800+ rpm at 31 mph. This is tidal and incoming from 18 miles downstream so river current was slowed a bit. The motor trim was critical though and very touchy. On the way back home there was a wind chop. We opened it up again and couldn't get past 5400 rmp at 28+ mph before it would ventilate. [img]https://i.imgur.com/60W426T.jpg[/img] [img]https://i.imgur.com/VpUIkVy.jpg[/img] Here's how it looked running: [img]https://i.imgur.com/LTgRsL0.jpg[/img] [youtube]HvHs1OvL3pA[/youtube] I'm going to drop the engine down a bit.
