Trim problem on new Futura with 20hp
First trip out yesterday on my new (smaller) Zodiac Futura - it's a MK1 3.5m with a 2003 20hp Mariner 2 stroke. It was a pig to get up on the plane even on the lowest setting: the bow just went up and my son and I had to move forwards and it would eventually go, though not always with ease or without stopping and trying again. It flew then at 28 knots.
Not terribly satisfactory. The boat has speed tubes and is rated to 23kw (30hp) but may be it's too heavy and I'm going to try my 15hp Mariner 2 stroke that I was going to sell. We tried trimming up but, as expected, that made it worse. Perhaps a doel / whale fin will help unless anyone has any other suggestions?
