    Default Starting Engine Out of the Water with Garden Hose

    It has been some years since I owned a jet boat and should have my new one to me running today. The boat has a Log exhaust system and I know your not supposed to run the pump dry so here is question. With the garden hose hooked up how much water needs to running through the water hook up when you are first starting the boat? I always had Bassets with a check valve so I was never worried about water getting in thru the exhaust when cranking the engine over but I am not sure how the Logs internally route the water and how much flow is required.

    Thanks,

    Joe

    If you elect to do this , light the motor then turn the hose/water supply on , Always kill the water before the engine (helps to have a "helper" for the hose bib ) Tom

    Tom,

    You have me confused with the "IF" in your statement.

    What "IS" the correct way to do this?

    Joe,
    Before you fire it off in the driveway, be sure to flush the pump out the best you can. Here's the stuff that came out of my new never been in the water pump after towing it home-




    As Tom mentioned, fire the engine off and then turn the water on....it really won't need much. When done, turn the water off before shutting the engine down. You really don't want the water circulating through the engine when it's not running, lots of not very good things can happen. Also keep in mind that most homes have a minimum of about 60lbs of water pressure, the engine only needs about 15.

    Good Idea CAS,

    The boat has been sitting at my friends for 10 years so there could be a Rabbit Den in mine!

    Have you tried to turn the pump by hand without the engine hooked up? After 10 yrs of sitting, I don't think I'd be running it without some investigation. Sorry if you've already done it, I haven't kept up on what you've been doing.

    It does spin freely, no weird noises etc. We had to pull the heads on the boat and I am just about done putting it back together. All I have left is hooking up the battery, priming the engine and then dropping in the distributor and firing it off (HOPEFULLY)! After that I have to get a new steering cable and then time to go to the lake for a test run. My friend pickled the boat really well until he showed it to a co-worker and then the last rain in Cal about a month ago got water into the intake. Water had surface rusted the stock cast iron manifold and heads so we felt it was better safe then sorry to pull the heads and do a valve job. The machine shop couldN't believe how clean the seats were considering how the manifold looked. So he just did a light 3 angle valve job and I replaced the intake and carb.

    He could pull the inspection cover off and spray a can of WD-40 or silicone spray on and around the wear ring as he spins it over by hand. I'd guess it wouldn't hurt

    damn i hate those spiders!

    remember too, even a few moments can screw up your rubber exhaust hoses..those things want water. I screwed up one time and ran it just for a little..and it bubbled them up from the inside. Now getr some pics and get that thing on the water! good luck

    echo that; been there...

    also, make sure the bow is up like it would be sitting in the water. if the bow's down, water in the exhaust can run the wrong way. i'm kinda nuts, but if the boat isn't level side to side, i'll put a jack under the low side and level it before starting.

    I used to have a shop that repaired boats years ago, the property my shop was on was backed up to State property, you could not let the water run off go down the storm drains (would have been good info. to have before I signed the lease) se la vi, I used a 55 gallon plastic drum with a couple of 1200 GPM 120 volt bilge pumps to run the engines on the "hose" the catch for the spent water went to a steel cattle trough half buried in the ground by the concrete pad, worked killer and I could get about two weeks out of the 55 Gal drum before I had to pump the water to the sanitary sewer drain. pain in the ass...

    Anyways, I use a Watts pressure regulator now for reducing the water pressure to about 20#, because the city water pressure here is about 85#, it is more than enough water pres. and I have a little 3/4" garden hose valve on the end of the hose and use an 8' section of hose so I can run the water from the drivers seat (I used to run five or six boats a day and it was a one man show for years)....
