    Chrylser 125 not revving past 4000 - or is it?

    My 84 Chrysler 125 on a 19' Bayliner Capri is now running very well except for a small backfire when starting and the usual smokiness. Out on the lake, the boat gets on the plane quickly and the engine is smooth - however it will not rev past 4000 on the tach. With just me in the boat, I...

    SUCCESS! 1984 Bayliner 19' + Chrysler 125HP - 40.7mph GPS!

    After quite a bit of tuning work on my Chrysler 125HP I finally water tested it today and with just me onboard and fairly calm water I got to 40.7mph using my iPhone GPS app. Interestingly the tach was still only showing about 4200 rpm which make me wonder if the tach itself is reading low -...

    125HP - slowly getting it sorted

    My 125 was never running really well and finally went to 2 cylinders so I've been working on her today. Thanks to another member I have a spare coil and spare CD box but I also found some wires rubbed bare under the flywheel. I had already rebuilt the carb and the fuel pump. So today I...

    84 125 Chrylser - troubleshooting help plz

    My 84 125hp was running OK at the weekend after I rebuilt the carbs - 35mph with 5 people, full gas tank on a 19' Bayliner - seemed to top out at 4000rpm but pulled ok. Went to take the boat out of the water today and it's having trouble starting and when I drive around to the ramp it's only...

    95 Seadoo Xp - newbie help needed

    I'm looking for some ideas on getting a 'new to me' XP running (717cc dual carb). The Ski has been sat unused in AZ for 3 years with an empty gas tank. I checked the oil, added 5 gallons of fresh gas and 2 new spark plugs and dropped some 50:1 mix into the cylinders before turning it over -...

    125HP - carb reassembly

    I stripped down my carbs today and have a question about reassembly On one of the bowls, the center bolt had a red fiber washer on the outside and another on the inside - the other bowl only had one on the outside Which is correct? Should the bowl form a (tight) seal with the stem of the jet...

    Random dying at full throttle

    Went out on the lake today and had an interesting experience After all my repairs and maintenance, my Chrysler 125 runs sweetly - get's up on plane quickly and the boat cruises at 35mph @ 3800 and seems happy to do that constantly. If I push it to full throttle I'm doing 42mph @ 4200 rpm...

    Backfires when it starts but runs fine

    OK, time for me to ask a question that has me stumped :) 125 Chrysler 1984 New sparkplugs, WOT timing @ 30 degrees, Carb mixture 'ideal to a touch rich', link & sync completed, choke works Every time I start the engine whether it's hot or cold it backfires once through the exhaust. Regular as...

    Bayliner Capri 1900 - to hydrofoil or not?

    I have a 19' Bayliner Capri with the Chrysler 125 OB. The previous owner had installed a hydrofoil on the outboard and it's obviously been there for a long time. The boat does plane at very low speeds - maybe 15mph or so - but I know that one or two on the forum consider them to be a waste of...

    Boat misting system

    Most of you probably wonder why on earth I would want a misting system when I have the lake 4' under my feet - to those of you who live in Arizona you will know EXACTLY why I want one :) Seriously, boating in 115F and 4% humidity needs all the cooling effects that we can get. Here's my plan...

    Cannot find a low cost GPH meter!!

    I have looked everywhere and yet I cannot find a low cost GPH (Gallons Per Hour) fuel consumption meter or computer! I have found Floscan etc who will sell you a $300 gauge and sender but I'm amazed that there is no $50 unit out there as the technology is very simple. An inline flow sensor can...

    1979 22' Starcraft SuperSport V5 Restoration

    Re: 1979 22' Starcraft SuperSport V5 Restoration Well you tested the transom :) But I don't think you tested your new rivets! Why not just float her out there still attached to the winch strap?

    1984 Chrysler 125 parts

    I was adjusting the timing on my Chrysler 125 yesterday and when I tightened the locking nut, the plastic piece that it snubs up against on the timing rod fractured. Does anyone still do replacement parts for this motor - I mean weird stuff like this piece? Thanks!

    Floor repair - am I doing it right?

    I had a rotten section of floor behind the starboard seats on my 1984 Bayliner Capri 1900 and I really feared the worst. I have been putting it off but decided today to tackle it before it gets too hot here in AZ Despite the worst fears, it turned out great - I think that the previous owner...

    Temperature gauge revisited

    Re: Temperature gauge revisited I just managed to remove the stainless steel screw on the top of my 1984 Chrysler 125. I broke 2 bits on my hand held impact driver, tried heating it etc and it would not move. A friend came round with is 20V Lithium Impact Driver and in 6 seconds had it removed...

    Temperature gauge revisited

    The old thread was closed so sorry for re-opening it. I want to add a dash temperature gauge and found an electric one with a 1/8" npt threaded sender. So now I need to remove the slotted screw on the top of the motor but I have already broken two slotted bits on my impact driver and if I hit...

    Needle replacement in situ

    I have a new set of needles arriving on Monday - the top one leaks when the primer bulb is pressed so I'll do both at the same time. Should I replace the needle and the seat as a unit? Can I drop the bowl, pull the float pin and replace the needle/seat or should I dismount the carbs and do it...

    1984 Chrysler 125 - at what revs is max advance?

    Can someone tell me at what RPM the maximum advance occurs? I want to do a dynamic timing check on my Chrysler 125 and would prefer to do it at as slow a speed as possible - not screaming across the lake at 45mph :) I know with cars that a lot of engines will have their maximum advance a long...

    Transom repair question

    I have a friend who has discovered rot in his transom and we were thinking about it last night. The f/g is very thick on the inside and outside of the transom - probably about 1.5" of ply between. Would it be possible to remove the top of the transom, dig out all of the old plywood using long...
