    Ran with no gear oil :( 2015 4 stroke 30hp

    Its always a good idea to change all the fluids in any used equipment you buy. With that practice, you would have caught the fact and saved yourself bundles. On something that I think is in OK condition but hasn't been operated for a long time, I buy it just on sight and get home and get...

    Question regarding prop shaft

    SS comes in all flavors and mixes. If any iron is in the steel which is normally the case on OB shafts with Chrome and Nickel, you will attract a magnet. Also on some SS props you will notice corrosion as I have seen and discussions are all over about combating it. OMCs first SS prop was the...

    Mariner DVA readings at ignition coil

    The DVA is a sample and hold circuit. The trigger pulses are narrow with a long rest time. To get a meter to read such, you need a storage element (capacitor) to "hold" the voltage sampled when the trigger fires. With your DVA working best when the rest time is greatest, I'd say it and your...

    spun prop?

    I assume that model of the Chrysler/Force has the geartrain setup like Mercury in that F contains an overrun clutch for times when you are at some speed and cut the throttle...allowing the engine to slow but the prop to follow the rotational pressure caused by the water passing over it at the...

    Trouble getting on plane

    The boat in my Avatar is my stock 90 hp 2 stroke (2.33 gearbox) pushing my 16 1/2' aluminum bass boat kissing 50 MPH with a Ballistic 13x24 3 blade SS. Add a person and I could do 45 easily. I also had a 21P of the same prop and would overrev easily at WOT....not enough pitch. My best hole...

    Measurements of Chrysler flared washer/spacer and long cone

    I miss Frank too. Enjoyed his posts and being a previous Chrysler owner (2 engines), could relate to his posting. I do recall him playing around with an engine in the 60-70 hp class, 3 cyl I think. There was something distinctly different about that engine that attracted his attention. He...

    happy happy joy joy

    Fuel consumption on those big bore, low rpm OMC engines is why they engineered "Loop charging" 10 years later introduced in the 3 cylinder Triump 55 hp.....cut the fuel consumption in half besides redoing the lower unit and prop style/RPM and all that for a totally different OMC...

    Top Speed Issues

    Thats high enough for adjustments to fuel air ratio. There are charts on the www to help you size correctly. I think my service manual has a chart for my 3-4 cyl 2 stroke OBs.

    Question regarding prop shaft

    You can bet the drive line...prop shaft and drive shaft from engine to lower unit are solid SS.

    Bass Boat Seat Pedestal Question

    I had 2" on my '89 630. Don't remember if they were operator adjustable or not. Course it was the back troll layout and all the seats were on pedestals.

    Boat keeps porpoising.

    That is what I was thinking.....hull has a "hook" from sitting on a trailer with inadequate support. But, learning how to drive your boat really has the most to do with it.....pretty much.

    Measurements of Chrysler flared washer/spacer and long cone

    Nothing magical about it. The OD at the prop is the OD at the rear of the prop casting or slightly smaller...a few mm. On length, the taper would terminate at the rear of the LU casting. Just how much performance improvement I have no idea. I had a 1971 85 hp with the cone and my answer is...

    Question regarding prop shaft

    No idea really but usually the prop shaft has a thrust washer for the prop to push against on the shaft, tapered for a tight fit on Merc. engines and then the prop (if pressed hub no accessories) and then some sort of retainer. On removable hubs, you have the hub and the prop shell. On Merc...

    1997 mercury 115 hp

    I run with about 10* of positive tilt out (LU away from the boat) when running below 2k RPM. It's not rocket science for me. I can be in the no wake zone with the engine tucked in and notice the engine vibrating somewhat and all I do is trim the rear of the engine up slightly as mentioned...

    Anybody ever hear of this one?

    You are lucky you could shut the engine down. Paraphrasing what Faztbullet said, one day I was in the driveway, on muffs, working on my linkage on a 90 hp 2 stroke looper and I got the timing too fast (somewhere in excess of 22* BTDC I guess) and the engine took off on its own (pre-ignition...

    1987 Rager 373 Battery

    No. Some SWAGs: Trolling motor is probably 24 volt and it may have a 12v option so you may have 3 wires going from your 2 TM batteries to your TM and it may have a 50 amp circuit breaker somewhere...probably at the batteries. That usually is a separately wired item. Everything else runs off...

    Outboard alarm sounds with engine turned off

    That's interesting. On Mercury engines the alarm voltage is supplied via the key switch in On and Start. If the post was for a Mercury I would say the key switch was in need of replacing due to bleed voltage internally pin to pin. Course to go with that you would have to add a bonafide alarm...

    Engine is running fine but no power would lack of engine kill laynyard be the problem?

    The lanyard connects to an engine kill switch. If it is in the off position, your engine will not run period. Your problem could be numerous things and usually fall into 1 of 2 categories...fuel or ignition related. You have to figure out which and then proceed to supply us with data to help...

    Info on alumacraft

    Friend had a side mounted console on that boat (don't know the model number change) and ran a 33 Johnson on it. A tiller 25 will give you some fun times with that FD back in original layout. I had a 12' with a 9.9 McCullough and there were several in our boating circle. Very popular, clean...
