    Default Need help with boat/pump identification

    Hi,

    I recently purchased a Marlin boat off eBay and am shipping it to Russia, Moscow.
    The paperwork says it's Marlin but I couldn't find a similar Marlin on the web. I also don't know the model name for this one.
    Has anyone seen one like this before?

    I am also having difficulty identifying the model of the Berkeley jet installed (I acquired a spare one plus the spare cylinder block with the boat as seen in the pics).
    I want to install the place diverter for this one.

    The Olds motor was built by Mondello in CA. The previous owner told me to pour diesel oil in but I don't understand why I would want to do that.

    Some specs:
    Berkeley Jet Drive with aggressor "B" impellor in pump.
    455 olds. The crank has been cut .010 (rods and mains). The block has been bored .040 over. Compression 9:1. It has "C" casting head with new valves, guides, and new valve seats. The valve train consists of Crane roller rockers and Crane push rod guide plates. On top of the motor sits an aluminum Elderbrock intake and an Elderbrock carburetor. There is a comp camshaft in too. High volume oil pump. A 10 quart oil pan, a 10 gallon fuel tank.

    Nice Marlin, here are a couple examples of Marlin boats.

    http://www.teshio.com/JetBoat/marlin.html

    As for the Diesel oil, that may be for the extra zinc content in the oils, they get removed EPA requirements here, in regular oil. With out zinc, the lifespan on a high performance flat tappet cam is reduced.

    Enjoy the new toy!

    Thanks!
    I've seen that page but only after a second look now I recognized that the green boat does indeed look similar to mine.

    What about the jet? Do you happen to know the model?

    Both pumps are Berkeley split bowls and non-insert types. The only difference between the Berkeleys is the bowl so it doesn't really matter if it's a B, G, C, or any other. The pump that's currently installed in the boat appears to have a non-Berk bowl on it, but I can't tell which (AT, Dominator). Whichever, it was probably put on because it flows more than the stock bowl. Or the pump could've started out as a C model which is a non-split bowl and they replaced it with the bowl that's on there now.

    There will be a metal tag affixed to the top of the pump. It will tell you what model it was when it left the factory. Doesn't necessarily tell you what it is now though. Most undergo changes over the years which this one obviously has.

    Thanks Squirtcha!
    Does that mean that in order to go faster than now I will have to again upgrade both the bowl and impeller? (that would be A-impeller I guess)

    Looks like agressor bowl:

    First a disclaimer.........

    If any of the information I gave you above is incorrect, someone will jump in and straighten me out.

    The bowl should be fine. It's probably a better piece than a stock Berkeley bowl would be.

    Impeller change/selection etc. is a whole other subject. If it really is an A cut it'll probably be about right. When you get some max speed and rpm numbers it'll be easier to tell. Typically with the Olds you don't want to wind em up too much (keep rpms at around 5000).

    If I'm reading this correctly, you haven't received the boat yet and you're already talking about going faster?

    That's funny.

    Have fun with the new toy. I don't imagine you see too many jets in Russia?

    That's right, the boast is shipping right now.
    Getting anything larger than a matchbox from US to Russia takes months and I want to be ready for the season (April). That means having to guess what I will need to upgrade without having the boat.
    According to the owner the boat goes about 50mph. I wanna see what it would take to raise that to 70mph without overrevving (4.6-4.8k rpm). The engine has enough torq to pull a tougher pump.

    The only jets we have here is BRP & Yamaha kind of stuff. That's in the west part. Siberia has huge mountain rivers and they primarily use aluminium jets (probably similar to Alaska).

    I noticed there is not a Place diverter on the pump. This is something you would want to add that is ususally good for a few mph. It is also fun for the rooster tail. You may also consider having the pump machined for a shoe and ride plate, also talk to one the jet pump shops about a loader. Pump upgrades will help out with the efficiency of the boat and help pick up speed and ride quality. As far as the motor I don't know much about OLDS engines, but headers are usually a good for several Hp over the log manifolds.

    Hate to hyjack but i got to ask.. How much did it run you to ship to Russia? I shipped across the US and that was a pretty penny so i cant imagine to another continent.

    Edit: Oh and welcome to the site.. Send pics of it running once you get it...

    An Adapt a shoe and ride plate kit would be my first suggestion to make the boat Faster! after Investigating the condition of the pump.

    From Michigan to NJ - $510, 670 miles (through lowest bid at uShip)
    From NJ to Finland - $1900

    Shipping across US is best through uShip or if you do long distance, probably a container on the rail is cheapest.

    Eugene congratulations on your purchase, sound like quite an endeavor! Although 70 may be a lofty goal , you should be able to improve the performance with significantly with trim (Place Diverter or Turbine trim) as said earlier here in this thread .That particular boat hull was very popular here in the early 70's and was reproduced by several builders I recently shipped a very similar hull to West Africa (Cammaroon) last year . 455 Olds were very popular and Joe Mondellos (my neighbor in Paso) was a pioneer in Olds performance. Welcome to the Performance Boats forums and good luck with your Project , BTW I have a frieind in Belarus who "dabbles" in these types of crafts and performance BMW's as well Tom

    Just a note re shipping ,I'm sending a boat to Germany (in a container) cost is $1600 + or- , but I just got a quote to haul an 18' Sanger to Philly PA was almost $1900 We use a company in Paramount called CFL freight lines

    Sleekcraft to West Africa

    Thanks everyone for your warm welcome and for the suggestions.
    So far I have decided to go with the place diverter.
    I've been monitoring this part on eBay for a while now and it seems they don't come up too often.
    I know that both jetboatperformance and berkeley website offer these so if I don't find used, I will purchase from there.

    As for the rest of the modifications - this will have to wait until the boat is over here so I can inspect it first.

    We don't seem to have even a single boat like this in Moscow or in Russia. Needless to say that we have any workshops that understand these types of jets.
    My boat will be serviced by a car workshop that specializes in the US cars.

    Hey Eugene,

    Yep, I agree, just like in the AK (Alaska).
    We are in the same boat, so to speak, nearly everyone has an aluminum river boat here.

    The looks you will get while towing it around are going to be half the fun!

    I dig the Olds too
