@Shepperd, Sorry fot the late reply. I am not very technical, so the maintenance part is done by a specialist. I saw him takeoff the heckdrive and I trust him he will do all the things necessary to the boat, it is all done before the season. Thx for the advice. The last suggestion you did I will look into, is seadek also softer for the knees? That would be a big improvement, how long will that stuff typically last? Well had great fun again yesterday waterskiing and still very happy with the boat! In Holland where I live we don t see al lot of Chaparral s, more Four winns, must be because the dutch dealer is next door.
