I just bought a 1987 Thundercraft Regency 16ft with a 2.3 liter Ford. The timing belt broke and the boat had been sitting, water got in and locked it up. I now have the motor free but it only turns so far befor it stops. I think it bent the valves. My question is if I go to the local auto junk yard will I be able to use a 2.3 out of a ford truck or car?

not sure if they will swap, but the 2.3 in a car doesn't bend valves when the belt brakes

Is the automotive engine a timing chain?Rather than a belt?

I need a new prop for a 1989 spectrum. Its 19' with a 2.3 liter cobra sterndrive. The old prop was a 3 blade aluminum and 13 3/4" diam 15 pitch. I'm trying to increase my "hole shot" without sacrificing too much top end speed. I'd like to be able to pull a skier out of the water. Any suggestions?

a 19' with a 2.3 is never going to be much of a ski boat. I would stick with the 15 and just practice the skiing - 2 skis and then drop one if you want to slalom. 1 driver, 1 spotter, 1 skier...leave everyone else on shore.

I have reason to suspect that the Holey carb. from a 5.8l V8 cobra is not allowing fuel in. It hasnt seen active service for a long time and the separator/filter had a fair bit of water in it. Should I be able to blow in through the fuel intake pipe coupling ? it appears to be blocked. Is it possible to dissmantle without interfering with adjustments/settings ?

Dustin....and many others in this thread. You should be starting your own NEW thread when asking a question, this is one of the worst ones I've seen in a while for new people just tacking their question into someone else's thread. It makes it very confusing to follow along.

Anyway for your carb problem it really just sounds like the accelerator pump isn't working. Take the flame arrestor off and look down in the throat, when you pump the throttle do you see any stream of gas shooting out? You can pickup a kit and rebuild it or take it into any carb shop and have it done.

Just make sure the engine is not running. If it is and it backfires through the carb well you can figer out what happens

I have a 86 sylvan, 17' 2.3 It ran fine when I put it away last year but now I have no spark to the plugs. No spark to the points. The coil shows hot, in and out, and I have juice to the wire inside the cap that feeds the points. What is it? Condenser, coil, points, fuse? HELP!!! I just want to go fishin.

Brian....I am 99% sure it's probably your points. Take a piece of fine sandpaper or an emery board or ??? and give the points a quick cleaning to see if that helps. If it does then don't leave it like that but replace them, set them for the proper gap/dwell and check/adjust your timing.

As above check your points for correct operation, they must open and close as you crank the engine, make sure they are clean and gapped correctly. You can have all the power in the right places but if the points don't open/close with a good ground the coil will never charge and collapse creating the spark.

I just bought a 1989 Bayliner 1952 with 2.3 ford omc cobra engine. The engine starts fine etc the problem is when I go to take of it hesitates/sputters and sometimes stalls.
Once it gets past this little hesitation point it seems to run well. The old owner told be that the boat was not used much and a mechanic told him that is was just from a lack of running. I have been told it could be the points? or the boat needs a good tune up.


Any thoughts

Thanks

Probably needs a good tune up including fuel filters. Your problem could even be the accelerator pump in the carb. Start with the tune up and filters, pull off the anti-syphon valve at the gas tank (where the engine fuel line attaches) and clean it good with carb cleaner and see how it runs after those things are done.

Bob I am planning on doing some work on the boat this weekend.
Can you advise what exactly you mean by tune up?
Change of plugs, wires and filters?
Also where exactly is the accelerator pump


Thanks

The accelerator pump is inside the carburetor.

A tune means different things for different people.

Distributor Cap, Rotor, Spark Plugs, Spark plug wires, Distributor Points & Condensor, Changing Fuel Filter(s), Changing Engine Oil & Filter. Checking or changing accessorie belts. Checking and cleaning Fuses, Cleaning the carb with carb cleaner and Flame Arrestor with soap & water.

you fill outdrives from the bottom up, remove the upper most screw and fill with the drive as straight up and down as you can, till it just comes out the top, UNLESS you have a screw on the very very top ( not top side ) of the drive, then it's only to the Notch on the Long Screw.

Dont touch the screw on the PORT/Left Side in the middle.
Ok ?

Thanks Brian perhaps you have a diagram that could help me out a little more?
I learned the hard way about the screw on the left side (what a stupid set up)
We had to take the outdrive apart to fix this.
The bottom most screw is on the bottom fin? Is this correct?
If so the only one I would need to locate is the top one. Again if you had a diagram for me and point these out that would be great I would like to get the boat in the water this weekend.
Again Brian thanks for your help.

Shows #60 on the top ( mini dipstick ) - dougrussell.com is a marina near me in NE, has some nice pics, but is limited in year range.

yea.. the bottom is on the bottom of the FIN..

You should use the wides screw driver you have.

There is an Impact Driver set you can buy that is Perfect for stubborn screws that has a big flat blade bit in there you can put on a 3/8 drive rachet. and the impact is great if they are tight, a tap of the hammer while twisting with the wrist.. viola !

your welcome...

First thing to check is the impeller in the drive water pump. if it has fins missing then you need to check through the system as they can cause blockages.

Gents I have having some RPM issues
Full out the RPM's are 5600 (way too hi)
I have been told I need to change my prop.
currently I have a 13 1/4 X 17 prop on
any advice on what I need to put on?
What should the RPM's be?
The boat I have is a 1989 Bayliner Capri 1952.
Also any ideas of a website that will tell me which prop I need and also a website that I can buy on for a half decent price.


Thanks

Harry...the 2.3 is a high RPM motor, specs for WOT are 5200-5600, you could go up 2 in of pitch to a 19" prop and that will probably bring your WOT RPM's down between 300-400, you may see a slight decline in your hole shot but may actually increase your top end speed a bit.

There are lots of websites out there but ideally you want a prop that will put you withing the manufactures suggested RPM's at WOT.

Some marinas/dealers will let you try different props before buying.

How is that possible when it red lines at about 5000 or 5100 RPM? Bayliner has told it full out it should be around 4800

This is the initial setting for this screw. You turn it in carefully until it bottoms out, (don't want to damage the tip or the seat) and then you turn it out 1/2 turn and go from there. See # 15 in the pic below, this is the idle mixture screw.

Hi. Could it be possible there`s a miss in the manual when it says, idle mixture screw 2 1/2 turns out on a 1987 2,3L model and on all other 1988-1990 2,3L models 1/2 turn out? The other tune up specs are exactly the same. What do you think?
Sorry for jumping in like this.

If you do a search, you will find that there is a different part number (carb assy) from 88 and up.

I agree with Bob,idle mixture turn outs are general, due to the age and condition of the carb. adjustment could vary significantly. The use of a vacuum gauge on a straight source of vacuum, not ported vacuum is a sure bet for proper adjustment

Harry...your winterizing question most likely got overlooked. It's always best to start a new thread with your question so this doesn't happen. Not to mention it's not good forum etiquette to tag onto another's thread with an unrelated question. Have a read through this page and then come back with any specific questions (in a new thread)
