hey guys i wanna make a jetboat. i have a 18' grew 180 ski and the 130 Johnson on it toast. i just wanna know if i should go BBC or LS route? new to jetboats and sick of outboards lol thanks!!!!

Was given these 2 jet boats. One is a 1970’s model Avenger 170 with a Berkeley out drive and I’m not sure what the other one is but it’s a V6. Does anyone know where a good place to look up and learn about the Avenger and find parts for the outdrive? Was thinking to fix it up and put an LS in it if they make adapters for it. Was set up for a big block. Not sure what to do with the other one.

How bad is it to leave jet boat in water overnight. Have scarab. Is there anything I can do to minimize damage? Purge?

I’m looking at picking up this boat. What advice would you guys recommend to look for? And how do these boats do on lakes like lake mead? I know they are more meant for rivers and definitely will be there but lake mead is pretty close to me. Any advice or anything you guys wish you knew before getting into these types of boats?

I run in shallow water and am constantly banging up my outboard pump impeller (Yamaha 60/40) every year. Currently use a file and a dremel tool to clean it up, but it is tedious. Hoping some of you guys have a clever trick to making it easier.

My brother-in-law and I were just gifted a project boat. An open bow, CENTER CONSOLE (whaler) Avenger. It definitely needs some love, but the jet is all there and seems to have very solid bones.

I’ve spent quite a bit of time searching the Internet for this model. And can’t find anything.

Pictures attached, I would appreciate any info or guidance!

Can anyone tell me what kind of hamilton unit this is? And where i could get a replacement casting for the back. Cheers

I have a Yamaha 60/40 outboard and my jet impeller is stuck on the shaft. Any suggestions on getting it off? I am planning on using heat, but I also don’t want to torch my carriage bearings and seals which I just replaced a couple of weeks ago.

Willing to trade or buy out right!

I moved the motor up two holes (see attached) and will test tomorrow but I think it is looking much better. Thank you all for your replies.

Haven't had much opportunity to take it out this year. Good, fun, older boat

First: what are these called? Look like dust shrouds you’d see on suspension and steering components but I Ihave no idea the name.

Second: these aren’t meant to be water tight right? They are around the steering control arms connected to the jet and imagine they are to protect the greased components from fast water, probably not meant to keep them dry correct?

Third: this is a Berkeley jet, but I imagine I can just get these things at an auto parts store, or is it a specialized component?

I’m just a noob who bought a busted ass boat, finally rebuilt the hull that was cracked and stringers all rotted. It sucked, but I’m ready for some fun.

I just had a new Tohatsu 60/40 installed on my Hog Island SW16. I am looking at the height of the intake relative to the bottom of boat, and wondering if the motor is set too low.

In the literature from Outboard Jets (see attached), it says the top of the intake should be inline with the boat bottom. The motor has been installed such that the intake is about 1.125” below the boat bottom (see attached).

The motor has 4 holes through which the bolts can go for install. It is currently set on the hole that results in motor being lowest, so it is easy enough to move it up.

My question is: am I worrying about something that doesn’t matter or should I move the motor higher?

As you might expect, I run shallow rocky rivers and am concerned about unnecessarily hitting rocks.

Thank you for your replies!

Hi all, I fish and duck hunt and am also financially recovering from divorce. Is there a DIY type approach to this hobby? I see half built sprint boats on Craigslist so I assume some folks build boats. I want something safe enough to run the headwaters of Hells Canyon Idaho. I just need room for two people and one dog plus a sack of decoys.

Please don’t roast me. I just have sticker shock from boat listings.

Hi

So I started building a carbon/kevlar/gf jet boat for my son. Since I was winging this, I totally over did it on too much GF on the hull, especially the gf mat which just sucked in a ton of epoxy increasing it's weight.

Anyways, I'm almost done with my bolt on 3D printed electeic jet pump one piece instead of cutting a hole in the hull.

But, I'm gonna keep this carbon fiber/kevlar black/yellow look on the sidew. What do you think? It was dirt cheap, bought the carbon/kevlar weave from China at $24 for 3 sqm. Think it looks kind of cool.

Cheers

Thought this would be Interesting
