Hauled the boat to Newport over the weekend and put two hours on the new motor in Yaquina bay. Had a couple of non-motor related problems to work through. Biggest issue was the deck drains leaked , quick trip to England’s and a couple hours to get sealed up. Launched around 1:00 PM with a heavy North wind blowing around 15 knt’s. Stopped by the fuel dock and topped off the tank then out to see how the motor ran.
First impression was good, the motor starts with just a touch of the key, takes about a half second to fire and no choke to fool with. Very quite at idle and when underway compared to the Yamaha.
One person, full tank of gas, half tank of water. While not a heavy load not exactly a light load either. Temp was around 65, wind blowing at 15 knts’ solid 1 foot chop on the bay.
Still some work to do on getting the correct prop, the 15 x 15 gave 5450 rpm and 37 mph did not get fuel usage numbers at the top end. Looking for around 5700 rpm ideally, will return the 15 x 15 and see what we can come up with.
After the top end run I did several runs around 21 to 25 mph. At 21 mph 2450 rpm and 6.9 to 7.0 gph fuel for a solid 3 mpg.
25 mph 2800 RPM 8.1 gph once again 3 mpg. Only time I ever saw 3 mpg with the Yamaha was just off idle so very pleased with the numbers.
On the way back in I did some non-planning runs. At 6.3 mph was only burning .94 to .97 gph for 6.4 mpg. Need to run these again as there was some outgoing tide helping but the wind was quartering off the bow and was going directly into a 1 foot chop.
Very happy with the performance, still working through the gauge setups to get the displays the way I want. Really like the I Command gauges just a lot of options on display types and combinations to pick from.
Comes up on plane and accelerates like a whole new boat. Can't wait to get in a fishing trip and some ocean time.
