| Which engine?
New boat (38ft cat, slim hulls) with standard twin 20HP, optional 30, 40HP. Which to go for? difficult to change later.... One argument: 20HP lighter, less gph, adequate performance, Autoprop would give extra power when punching into seas/headwind as it auto-pitches (and that is the only time you may need it) so spend less on Autoprop and go with smaller engine. Other argument: 30Hp allows cruising at lower revs, better passage making on one engine, extra power for motoring into bad weather, but probably only half knot faster and extra weight/expense Use will be blue water cruising Any experience/thoughts? |
