Jet Boat??

[BoatnAround]

Does anyone know what the value of a 20' 1978 Sundown Marine Jet Boat is? Also, where can I get more information about the boat. It seems like it is not a very common boat and I can't seem to find anything about it. I am looking at one that is for sale. It is in decent shape and has a 455 big block. Thanks in advance!!

never heard of that particular brand but did you try www.nadaguides.com they may have it listed and can give you a value if they do

Boats are not like cars/trucks. Most boat makers are small and tend to not be in busines very long.<br /><br />You have three threads going on this boat. It's getting hard to follow.

Most '70s jets with big blocks go for around $3-5 grand depending on the condition.

Re: Jet Boat??

Great! Thanks everyone. I actually bought the boat. It actually has a 454 Chevy in it. Worked on the engine last week and should have it running this weekend. It has a berkley Jet drive. Does anyone know how to run it out of water??

I'm not sure--I have a newer Sea-Doo jetboat. you can try Tim Place at placediverter.com They make a lot of Berkley jet parts (and go-fast accessories) Tim was very helpful when I purchased a trim late for my Merc jet<br />good luck!!

Re: Jet Boat??

From inside the boat, looking at the transom, there should be a water hose coming off the upper right side of the jet drive housing feeding water to the engine. Disconnect the hose and connect it to a garden hose. I was told you should minimize the amount of time you run a Berkeley jet out of the water as they are supposedly balanced when in the water and that undue wear will occur when out. I ran mine a few times out of the water and never had a problem. The shaft is supported on one side with a big ball bearing and the other with a bushing.

Thanks Navigator!<br /><br />I will only need to run it for a short period of time (just to see if the engine will run).
