I am too doing this soon....have many questions as well, but this is what i have gathered so far....maybe someone can chime in and fill in the gaps.

level the boat to zero. (via the stringers or bottom...or both ???)

then set the intake at 4 degrees via where the suction housing bolts onto the intake. Also make sure its zero from side to side in relation to the stringers.

as far as the process of applying the epoxy putty....i dont know. do you set the intake then pack in the putty? or do you cake on the putty then set/level the intake?

i was thinking of putting jacks under the boat holding the intake up and using the bolts to level it out then using putty to seal it up.

yes.

you will notice that the intake has 4 degrees in it. setting the top part 4 degrees will set the base of the intake into the boat at zero.

Not if you're measuring your angle on the suction housing flange. You want the intake to be 4* down to the rear on that flange. Level from side to side, square it up with the stringers, the transom and any other hard angles you can find. Post up some pics of what you have and what you're doing, I'm sure there will be someone along shortly that can help guide you, and teach the rest of us.

Good luck

yes, this is where the angle needs to be measured from, the intake is all one piece so if the flange is good, then the intake is good.

ok, so then his comment is correct saying its 4 degrees with the rear higher then the front  :thumbup:

Maybe I'm confused. I'm calling the rear of the intake/suction housing flange the point closest to the transom. Is there something I'm missing? I was under the impression that the intake needs to be installed so that the suction housing flange goes down angle toward the rear.

he is basically saying the rear part of the flange should be higher then the front of the flange. (ex not -4 degrees)  ...not the entire intake.  ;)

And that's what has me confused. In regard to the intake edge, NOT the suction housing flange, it should be zeroed out with the bottom of the hull. The suction housing flange is where your angle is measured. This is assuming the intake is going back in at the stock setting.

Ok so I checked the intake and the flange that the jet mounts to is 4 deg angled to the hull mounting flange this points the jet downward 4 deg from the hull when the intake is mounted level to the hull bottom SO to get the intake level with the hull bottom I need to have 4 deg on the jet mounting flange this will put the rear of the jet flange  lower than the front of the flange

Thank you Lucky Now how to prepare the hull and intake. Do I sand the hull area and the intake flange? i was advised to chisel the old epoxy out by someone and now I read where heat applied works well to so I guess I will try to heat the remaining parts off I did get into the fiberglass of the hull in 2 places (very minor) I will probably put fiber glass resin to repair these areas. Should I paint the intake flange with epoxy or appliance paint prior to installing it I know prep for paint is impotant not to worry I have been custom painting for over 30 years. Should I coat the hull area with paint as well I am afraid if I leave it sanded then if I ever need to remove it again it will be a b*tch.

I would get the epoxy area as clean as you can get it. Use some mineral spirits or denatured alcohol to clean it after you've got it roughed/sanded. I wouldn't paint the area the intake sits in, it will be covered with epoxy once the intake is set anyway so you won't see it. As for the intake, I'd rough sand the epoxy area, paint what you'll see once it's set. Mix up your epoxy, put some on the intake and some on the hull area. Set the intake, get it leveled and squared up and set some dead weight on it to keep it from moving on you. Not so much weight that it affects your set. You can tape off the hull so once the epoxy dries you can pull the tape and have a nice finished line, same thing on the bottom and on the intake itself.

I know this sounds obvious but also make sure the centerline of the itake is aimed right down the center of the keel. I've actually seen pumps mounted pointing left or right of center. Draw a line on the intake right down the center and then run a snap line from the keel center in the bow to the transom directly above the keel.  While you are getting all your angles right be sure to check that the line is directly over and straight with the snap line.
