Here's a wiring diagram and troubleshooting instructions for the Teleflex tachometer.

Guys....I did something retarded a few weeks ago. I decided it would look cool to put yellow bezels between my white gauges and white dash. When I removed the tach to slip the new bezel over it, my 8 year old son interrupted me and I got the wires mixed up and when I ran the motor, I burned up the tach. I now have a replacement tach and need some help as to where the wire go. I have the lighting and ground wires correct as they are the same as the other gauges however there is an Ign and send connection that I think I screwed up before. Does the ign plug take a direct 12v from the ignition and the send from the wire coming in from the distributor?

Sorry for the lameness....just want to get it right so I don't burn up another tach on Saturday when I install it.

Thank you.

We have about 15 boats in the club now and chat mainly on www.texashotboats.com . For the North Texas group, we mainly boat in Lake Lavon as it is the most family friendly and less busy lake in the region. We meet every Sunday in a cove and also on Wednesday evenings too. There's even more Hot Boats throughout Texas.

I've met some fantastic folks here and when you're ever in town again, stop by and look us up. Meanwhile follow the chatter on the THB website.

I frequent this site because the sheer numbers of jetboat owners is far superior to us here in N. Tx. You guys are a wealth of knowledge. 

Hey guys....I know this is a Socal forum however I visit because you guys have a ton of knowledge and many more boats than we have in North Texas. However, with that said....here's a video that was shot at our local lake this past Sunday 11/14/2010. Enjoy!!

To all those that have served past and present, I salute you.

Happy Veterans day!!

Thanks a million guys. I think I'm going to run a HOLLEY 850 CFM MODEL 4150 4 BARREL MARINE CARBURETOR

Part #: 0-80443. What to y'all think of this carb?

IRR. I am absolutely going to go with a Marine carb. Thanks for the explanation.

guys, i think we are looking at his cid 540 and saying that thing needs a BIG carb. now we know it wants more due to him changing to an 850 and picking up rpm and mph.

now that being said, what heads and cam do you have? you are running logs and the dominator may be too much depending on the heads and cam.

Ralph, I'm running DOVE-C heads and I'm not sure if they've been worked or not. I'm also running a Mallory ignition system.

Thanks IRR.

The guy I bought it from is a Ford mechanic near San Antonio and he said that he and his father in-law stroked the 460 to a 540.....and that's all I know. He said that it has a "Mild" cam in it however I'm really not sure what is really in it. I cant seem to get a hold of the PO so I either believe it is indeed stroked or I tear the motor down and check for myself.

I agree with you concerning the "Marine" carb.....I have small kids that are with me all the time and also since I spent 21 years in the Aviation field, both flying and fixing, I am a safety conscious person. I'll look into the 1050 marine Dominator and see what I can find.

I pulled the plugs and they are currently a "Dark paper bag brown" and didn't have any carbon built up on them.

Currently I have Hardin logs with snails for exhaust. I've also started looking into Water jacketed headers too.....just takes time. If I can't get the motor to"breath" there's no sense in spending a bunch of money on her to get her to run right. A new carb and intake would of course mean new exhaust too.

All it takes is money! Lol.

Thanks again.

A little more information is needed for you guys. When I bought the boat two months ago, it had a Mr. Gasket fuel pump, which I swapped out immediately. Also it had clogged fuel filters which were replaced with Wix fuel Filters. Also, I used 3/8 inch fuel line as replacement hose. Are you saying the 3/8 line is too small of a diameter?

The reason it quit on you and the fact that the carb is too small are two different issues.   Too small of a carb will not starve the engine of fuel.  And yes, you need more carb.  I'd run a dominator on
A 540

What size Dominator?

had a similar problem on the rogers except it would peg the needle way past 80 and we didnt have great oil pressure bc the pump was shot(Brand new pump) put in a new gauge and saw the incredibly low oil pressure... 

Ya, I just bought my Crusader a few months ago. The prior owner had an automobile sender to a marine guage so the Ohms were different. I put a marine sender on it and now the oil guage works properly.

Here's a roost from Texas!
