    Default Newbie Question - What does a Loader do?

    Please excuse this newby Jet Boat question but most all of my experience with anything loud and fun has been limited to cars, trucks, and 4 wheelers... now that I have a boat I was reading the thread about Loader failures and I looked ay my intake on my boat and didn't see anything that remotely looked like the pictures I had seen in the other thread. Mine has a grate over it and looks extremely well made into the actual fiberglass of the boat. I have recently built a new engine and HP is roughly double what it was so other than rebuilding the pump do I need to do anything with the water intake area?

    A loader helps feed water to the impeller. The rock grate on yours is to do exactly that, stop rocks from screwing up the impeller. Most boats (V bottom) came with a rock grate from the factory. A loader can help or really hurt performance if you have the wrong design for the amount of power you are running. What boat do you own and how much power? You might be better off just leaving the rock grate.

    Well... as far as the boat... I had always thought it was a 77 Taylor SJ but my title says "Homemade" ... It seems to be built real well with full stringers, Berkely pump, BBC, etc... and the wood in it is fantastic everywhere. It had a .020 over 454 with flattops and 402 oval port Chevy Truck heads from 1970 on it with 2 different casting numbers. Cam in it was a parts house stock type grind that would work with the stock springs per the owner before me so I figure it used to have around 300 to 350 HP... I just built a 496 BBC for it that we dynoed at 606 HP @ 5300 and 619 Torque @ 5000...Here are a couple of pics of the boat in the lake with the old motor...

    Yea the handle was a play on the Tin Indian in the boat. Very Nice engine builds. What kind of HP are you making? I'd love to make a little more HP out of the 400 in the boat but Pontiac's are so expensive to build I decided to keep it mild and reliable. The deck of your boat does not look like an SJ to me. Not sure what your boat is but the deck looks similar to my SleekCraft Rebel. Do you have a pic of the dash area and maybe the transom? Bigger pics would be helpful too.

    I see you are in OK. You should try to make the Outlaw GTG July 4-8 @ Broken Bow. It's big fun. Lots of jet boats there. You can see pics of event past @ http://youngbloodjetboats.com/

    Also, If you haven't already, you should hook up with the Okmulgee Hot Boat Association. Great group of guys and they are close to you. http://www.performanceboats.com/okmu...t-association/

    Punisher the "Homemade" designation is a name applied in some states by thier DMV's to boats of unknown origin (missing HIN, homebuilt etc) if your boat has an HIN on the transom its easily checked in the Coast guard data base (MIC) , Cool Pontiac stuff in the door slammers , Grew up with Muscle cars myself, re a Loader you didn't mention which Berkeley jet ? with your 350hp its not likley you would have benifited from it but when you "Up" the HP with your fresh BBC you'll need to consider several changes in your jet Tom

    Having a title that says "Homemade" is basically like having a salvage title for a car. Somewhere in your boats past the title got screwed up and they had to re-issue a pink. They can't re-title it as a Taylor so it now becomes a "Homemade." I had a 78 Challenger that was also a "Homemade", I later found out it was a theft recovery at one time.

    The engine in the picture on the dyno made 709 HP @ 6100 and 683 Torque... it is currently in main 69 drag car. It runs 9.90's at 136 in the 1/4. The blown motors I never dynoed and just used for cruise nights. The other aluminum headed 455 in the pictures made 650 HP @ 5800 and 650 torque and is in my street 69 GTO...


    I will see if I can get some better boat pictures. I have it all torn down now trying to get ready for this summer.


    I met the Okmulgee guys at that little one-way lake they have down there. Good bunch of folks but driving around that little lake was weird...

    Maybe we can make the Broken Bow deal this year. That would be cool!
