HI !!
We bought a Bayliner 3688 , 215 Hinos, 1994, and found out now that the boat is to slow... ( i know iknow how you can buy a boat without seetrail ... but we get it from a friend very cheap and know the problem before. )
The boat is not coming into Plane, and at full thrust it goes only 9 knts. ( cause its not getting into Plane )
My friend get on the wrong mechanic and the mechanic sold him other Props cause with the old ones ( we think that these ones are the original ) the boat only made 2200 RPM. ( sure cause the boat is not getting into Plane... my thinking )
Now the boat makes 3000rpm but even its not getting into plane, and move only at 9-10knts.
My thinking is that the props now only makes higher Engine RPM but not get the Power to bring the boat into plane.
I ask them if they check the Trim Tabs, my friend told the mechanic does, but as im finding out now the Tabs moving in a very short way, dont know how far they have to move !?!
My thinking is now to put the old Props on it and checking the Tabs.
So the real Question is , anybody knows with what kind of props the 3688 original comes with ?, how far the trim tabs have to move down ? is the 3688 only equipped with 2 Tabs ? ( cause my 32 had 4 ! )
Whats the top speed of the 3688 ( i heard its much faster then the 3288 and the 3888 )
Anybody knows what else could be the Problem ?? ( also was thinking about the turbos, but how i could check it ? )
WOULD BE SOOOOOO NICE IF SOMEBODY COULD HELP !!!:worth
THANKS !!!!!!!!!!!!!!!!!!!!!
