Jet Pumps / How to clean out pump?
« on: May 10, 2015, 10:23:05 pm »
I bought a TX-19 in Jan. The pump is set back to where the inspection cover is half in and half out of the transom. On my current boat I can pull the back of the boat on shore and pull the cover to clean out debri s that gets into the pump. Does anyone know how to clean out the pump with the cover half in and half out with the aluminum transom plate sealed to it? The reason I ask is down at Pirate Cove, I have had to clean out my pump on 4 different occasions to get the boat to move.

Engine Mechanical / Electrical / Sustained engine RPM
« on: May 09, 2015, 11:14:24 am »
Right now I am able to sustain 3800 rpm for 30min on a 19' jet with AA impeller. I am rebuilding the engine with all forged bottom end. Other than piston to cylinder and valve guide differences for marine engine, what else do I need so I can sustain 5000rpm for about 15min.

Engine Mechanical / Electrical / Update on 4.6 DOHC Turbo
« on: April 04, 2015, 11:23:48 am »
I installed a Ford 4.6 DOHC from a Lincoln Mark VIII in my jet boat 3 years ago. Last year i put a turbo in it. I had it built by a shop here in Las Vegas and run it through a air/water intercooler. I use stock lincoln exhaust manifolds which are stainless and merged them into a t-4 collector. I had it up to 8lbs of boost on a stock bottom end and ran 65mph on GPS in a heavy, read wet, 19' shallow V mini day at 4,800 rpm. I run a Legend pump with an AA impeller. I forgot to block a vacuum port on the carb and leaned it out. This melted the #7 spark plug which then filled with fuel and hydraulic'd the piston. It wondow'd the block. I had another one laying around and had it in the next day. I'm keeping it conservative until I get the forged rotating assembly in. Right now it is only showing 2lbs of boost at 4k and runs 42mph GPS Upriver in 7mph current. This engine and pump will be going into a TX-19, 500lb layup, and should be much more efficient

Engine Mechanical / Electrical / Fuel return line
« on: December 16, 2013, 10:15:55 am »
Ok, next problem. For the turbo application, I am running a walbro in-line fuel pump and an Aeromotive return-style regulator. I have 2 11 gallon saddle tanks. Any ideas on how to run the fuel return back to the tanks? I want to be able to switch from one tank to another so I don't lean out if one sucks dry before the other and once one runs dry, I know that its time to turn around and go back. Any ideas would be great.

Jet Pumps / Impeller size
« on: December 14, 2013, 09:44:39 am »
I posted on the engine tech about the turbo I am putting on my engine. Here is a link to what this combo will produce in a 2Valve engine. I am using an all aluminum 4 valve engine with much more flow capabilities. . It will be making at or more than 500 lb/ft of torque from 3500 rpm depending on how much boost I run . With this torque, should I be using an "A" or "AA". This will not be a racer, I just want to be able to cruise up or down river at 45/50ish and keep the rpms reasonable. I will also be doing a pump setback, getting the inspection hole outside the hull. PITA dragging the back of the boat up on shore so I can get all the grass sucked in at Pirate Cove out of the pump.

Any help would be greatly appreciated.

I posted this in Performance boats about a month ago and haven't gotten a response. Hoping someone over here will have some info on this. I have a 4.6 aluminum twin cam ford engine in a 19' Jet. Am putting a turbo (BW S475 1.10 AR 83mm with Air to Water intercooler) on it this winter and want to know if I can run the exhaust out the transom (single) without reversion/sucking water into engine. I will be addding water from engine cooling after the turbo to cool the exhaust, the plan was to run the exhaust down from the turbo then a 90* mandrel bend into the normal rubber tubing then out the transom. The 4.6 twin cam has a bit of overlap due to the twin cam 4valve arrangement. The turbo will be set about 1 1/2 feet above the transom. Should I be ok with this set up without worrying about sucking water back up? Thanks in advance for any help/info.

Topock / Laughlin / Pirate Cove 8/31-9/2

If anyone is going to be out, I'll be there. Yes, its a madhouse but I get there early. 9-930 is usually easy getn in. Pirate Cove charges $15 day to launch, but if U slip the boat for $15 the launch is included. This way for 2 days its only $15 and for 3 days it only $30 and that includes the $5 fee to beach. Usually stay in Needles and it's anywhere from $39 per night to $46. That's single occupancy. I never tell them 2 adults because they usually add on $10 more per night. And Topoc 66 is a Great place to spend some time.

Projects / Ford 4.6 DOHC
« on: June 04, 2012, 07:56:19 pm »
Well, i was gonna take a used 455 and rebuild it so it would survive in th water at high rpm. Not cost effective! Then thought about a BBC but again, cost of everything needed t do th swap. Well, saw a 18' at lake Mead and was running a 4.6 DOHC. Looked, sounded beautiful and it is fast enuf for me. Just shy of 70 on GPS. He made everything himself and agreed to help me. Under 3K for everything! Engine, ignition, mounts, headers... And he runs all day on around 6 gallons of fuel. If it works as well as hoping, will do same to my 21' Glen Coe also. Will keep everyone posted. You can see his engine on YouTube under Dr DOHC.

Jet Pumps / Berkeley or Jacuzzi pump??
« on: April 11, 2012, 07:46:44 pm »
I just bought a 2nd boat for parts. It's a 74 Glen Coe 21'. Has a 455olds and a Jacuzzi pump w trim. The hull has no interior and the floor flexes under foot real bad. Where the exhaust comes out the transom there is daylight. I originally bought it just for the engine to put in my '76 19' shallow V. This one has a Berkeley pump. My question is should I swap just engine, or the jets also?

Engine Mechanical / Electrical / Olds 350 build
« on: March 21, 2012, 01:37:40 pm »
Ok, got a 350 olds t replace th 260 in my boat. Want t do a basic rebuild. Cam, bearings, heads will b 455 heads, performer intake Hardin logs. Any suggestions on Cam, pistons for this engine in a '76 19' w/berkley jet. Built car engines before, but I'm sure there is a difference for marine. Any other suggestions would b great!

Engine Mechanical / Electrical / Olds 455 parts
« on: March 20, 2012, 12:24:32 pm »
I picked up a 1976 unknown make 19' with a 350 olds. At least thats what I thought. It runs just fine and I was adjusting the carb and saw the engine block number and decided to run it. It winds up being an Olds 260 V8. Now, the really interesting part. It has all Hardin Marine parts on it. Logs, front plate, bellhousing and valve covers. The valve covers say 455 Olds. I know that 455 heads will bold on to a small block Olds, my question is, are all the rest of the Hardin parts for a 455? And if so, I guess I could very easily switch it back over to a 455 if I can find one in the So Cal/NV/AZ area. Thanks for any help.
