    A brief insane moment and $300 purchase of 1994 Regal Rush

    I decided that since I bought the boat for the spares and really i mean REALLY didn't need it I did what I intended to do from the start. I pulled the engine and started evaluating it. The electrical plate on the side had been removed along with the jet parts and bent impeller, indicating to me...

    Mercury Sport Jet 120 blown........PLEASE HELP!!!

    From the manual on using the dealer fitting: Engine Flushing (Dealer Flushing Adapter) The engine can be started and run as necessary with a hose connected to the dealer flushing adapter. Do not, however, run the engine at wideopen throttle with no load on the jet drive impeller. 1. Disconnect...

    Mercury Sport Jet 120 blown........PLEASE HELP!!!

    Also when or if you refit the ride plate it needs to have a gas tight seal around the pump housing to keep exhaust and air out of the pump. The ride plate should be "flat" with the hull as well. If you or anyone is going to start the engine in the driveway use the "dealer" kit. You need to have...

    Mercury Sport Jet 120 blown........PLEASE HELP!!!

    Sometimes and possible most of the time the ride plate is bent by starting the engine without water on the dealer flush adapter that screws on the hose that attached with the brass flare (large) on the right side of the pump at the rear. What happens is one the engine might overheat if run long...

    Mercury Sport Jet 120 blown........PLEASE HELP!!!

    The hard part for me was getting the screws that hold the plate out. That and the inlet grate. The ride plate needs to be sealed to the hull and the pump body to prevent the exhaust from getting into the pump. The poor fit as far as streamlining etc probably would not keep the boat from getting...

    Mercury Sport Jet 120 blown........PLEASE HELP!!!

    Here is a link to a ride plate seal for your jet http://www.crowleymarine.com/parts/12290.cfm $64.99 If the seal leaks then the exhaust will get into the pump and cavitate.

    Mercury Sport Jet 120 blown........PLEASE HELP!!!

    If the ride plate and the gasket do not seal the area over the plate and exhaust is blown out and sucked into the pump the impeller will cavitate and the engine will rev high and produce little thrust. If the plate is bent you can perhaps straighten it and install a new gasket. The boat might...

    Mercury Sport Jet 120 blown........PLEASE HELP!!!

    The block is most likely the same and you can use it, but the crank has to be for the Jet, unless the 120 crank splines are the same as the 90 hp jet crank splines etc. I have NO experience with the 120 hp sport jet. My guess is that if you are willing to travel a little you might be able to...

    1996 Regal Rush XP 120 jet boat - Broken Control/Shift Cable

    Great write up I would do some things like that, but I lack the patience to record anything while I am working. I might take pictures to remind myself how something came apart. I think that I am going to strip the parts I need and scrap the rest. Keeping up two boats is probably more than I want...

    1996 Regal Rush XP 120 jet boat - Broken Control/Shift Cable

    I think that it is normal to creep forward in "neutral", but you could adjust the neutral position down a little and see if that helps. Make sure that you have the bucket out of the jet when forward or you will get vibrations. By the way do you need any Regal Rush parts? I have decided that the...

    1996 Regal Rush XP 120 jet boat - Broken Control/Shift Cable

    I think that if I remove the plywood piece behind the seat back I can get the fire extinguisher out. Lord knows how it got there. It is a white regular small fire extinguisher and a plastic mounting bracket. I think it will be easier to pull the plywood than the tank. I have pulled the carbs to...

    1996 Regal Rush XP 120 jet boat - Broken Control/Shift Cable

    My real question is the area under the seat where the floor of the cockpit drains. This seems to be in front of the gas tank and is inaccessible to get the fire extinguisher I can see a little of out. Unless it was left there to blow up in case of a fire and spread it more evenly. Trash and...

    1996 Regal Rush XP 120 jet boat - Broken Control/Shift Cable

    Surprise, Surprise! I bought a 1994 Regal Rush 90 hp boat the other day so now you and I are "in " the same boat! I bought mine for the spare parts, but it is a little good for scrapping. Unfortunately it has the threaded impeller which needs to be repaired and refurbished. Too bad I didn't have...

    Sugar Sands Tango randomly dies or won't start

    The hose with the hose fitting on it is the flushing adapter and not for running the engine out of the water, at least with the 90 and 120 hp motors. I have seen this in 175 manual excerpts as an additional cooling line for low speed operations. In the smaller engines there is a dealer engine...

    Mercury Sport Jet 120 blown........PLEASE HELP!!!

    The outboard will not fit since the splines in the crankshaft are different. If you do a search using Searchtempest.com on Craigslist you might well find a 120 sport jet engine or a boat with a good engine. I have seen several as I keep an eye out for a 90. I found a complete boat with the 90...

    A brief insane moment and $300 purchase of 1994 Regal Rush

    Whew! I got the threaded impeller off! There is some damage and I hope that Impros can fix the torn blade. Something must have gotten stuck between the impeller and the stator. Note the very rough home made impeller socket (welder not working correctly, but it held long enough to get the...

    A brief insane moment and $300 purchase of 1994 Regal Rush

    I have ordered an engine harness for a later model mercury electronics force with the ignition plugs for the CDM modules (three) to go with it. The trigger on the old style ignition and flywheel has four magnets stacked in the center ring where the trigger pickups are (for lack of a better...

    A brief insane moment and $300 purchase of 1994 Regal Rush

    OK here are some pictures. I need to take the steering wheel off and free up the shaft. Sitting for a few years has got some corrosion or other gunk in the shaft and it was frozen and now turns very stiff. I have knocked the starter Bendix back down from where it was stuck in the flywheel gear...
