The motor I have is a 25" shaft motor and am not going to buy a new hydraulic jackplate until i decide how much lift i will need. gonna be some fiberglassin' and sanding to get her going. I will take some pics and try to show what it looks like now. |
Sound like a load a fun coming up ! The pocket tunnels are a poor mans substitute for the real thing!!! but setting up as a starting point make the underside of you cav plate just above the level of the bottom of the hull . Gradually you can keep lifting till you get it to a point where its good for you and a little further and its doing all kinds a silly things .
CAVITATION when cornering is number one and second water starvation and a cooked motor when it gets really high for all out speed .So might have to look for a low level water pick up nose cone to add to you list for xmas goodies !!
Post some pictures if possible will and can help a lot !! and you could even get some really good advice !
The further back the motor the more you can raise it . But a 25 inch shaft ?? There are limits to all this you do realise ??
