Engine downsize final thoughts

Post by Ixneigh »

Performance eval

Its no 60 hp.
The 20 hp with flat pitch four bladed prop.
Low speed maneuvering is good. Decent reverse and turning. Better than expected. Top speed is hull speed for the boat.
Gas consumption at low speed (4.5 knots) seems equal to the sixty. (10 mpg) The flat pitch is a drawback there but they want a prop which will get max engine rpm WOT.
Seems like we gained 1/2 a knot in sailing speed.
Engine can be flushed at anchor using a pump bought off Temu for 25 bucks. I added desalt solution to the water. Note the etec was only flushed at the end of the season and it lasted 14 years.
