That strange steering deal was on the boat bad part is I let a real one go with the old hull. Will turn one out in the shop or call HTP. The alt mount is the challenge now thinking upside down is the way as u can see the conventional mount would require a lot of material removal on the plate. Was thinking you guys may have some pics of clean set ups so i can R&D them. R&D = Rob and Duplicate lol

Smaller alternator

I wanted to keep the alternator as low and out of the way as possible but couldn't get the full size to work like I wanted. Ended up buying a small frame 60 amp single wire, modified the mount plate, and got it pretty close to where I wanted. the pic isn't that clear, but hopefully you can make it out.

Things to plumb new fuel system: Roll of 1/2 inch aluminum fuel line CHECK, Flaring tool CHECK, AN fittings from tank to T then down to pump CHECK, Adel clamps CHECK, thread tape CHECK good fuel tanks NOT CHECK *^%$#

one tank was clean and ready the other looks like one tank had salt water in it. Has one hole in the bottom i can see may be others who knows, look at the pick ups WOW both from same boat.

New loader (from Duane at HTP) VS. old loader from ?????. Note weld quality (Tig/Mig) and solid vs stitch weld. Old loader did clean up well but no idea on its history or maker. This tub was parked for a LONG time so up dates were needed.

Got the motor in the old girl this weekend, wanted to hold off till the tanks were in but only have one built (shop crazy biz) the pump is at 4.5, motor is a tad more but it just looks wrong to me. Have put angle finder on pump, CV joint and motor. The numbers are good if any thing the joint may be to aligned. The feet are 4.5 back cut and the motor plate sits flush, carb pad and valve cover sat 5 deg. + some.
