Had a great nite last night after catching a bunch of muttons,vermilions and yellow tail we were comming in lost power and ran aground.The lower unit has a dent right on the noise cone couldn't get motor out of gear to start it.2 guys saved us helped get us off rocks and towed use in to the ramp( God bless them)The hull is fine the gear case is F--- I mean messed up.I going to take a look later.Anyone know were I can get a good gear case with breaking the bank let me know.After I fix that I can figure out how come I lost power in the first place.Like I said we had a great nite.

where did you run aground? did you run out off pompano or did you go south?
-
Hillsboro inlet on the north side.It was flat calm but the current was ripping.
-
What kind of motor do you have?
-
I havent been out hillsborough in a few years but i do remember some freakin awesome rockpiles on the north side. I guess its a worse feeling knowing they are there and you are powerless to stop the damage

I was freaking out to say the least.I think the guy that was with me had to change his shorts both of us just sat their a second before we moved.The motor is a 85' 175 johnson.

Check these guys out. They make NEW aftermarket lower units right here in Tampa.

Try Gulf Coast Marine Power in Bradenton Fl, 941-708-0393. He has parts to motors every where in his shop and if he doesn't have it he can point you in the right direction.
He normally doesn't answer the phone. Leave a message with motor info and what your looking for and he's pretty good at calling back.
I called him after posting this and left a message. Will let you know.
Shorts
He does possibly have one, pm me.

Replacing the lower unit would cost around $500 to $900 and the motor is a 25 year old Johnson 175.I don't like the idea of having that boat sit until I can re-power it.But putting alot of money(i don't have ) into that motor seem like a wast.I would like to put a 4 stroke 150 on it.I think that would be fine for me and save a lot of gas.If I can take not fishing without going nuts just have to get some info and pinch more pennies.

How do you know you need a new gear case. Is it cracked, leaking, skeg broken or just a dent. If it were me. I would get a manual on the engine, pull the lower unit and see whats up with it inside and see if you can save what you have. I am not suggesting bandaging something together. But, know what you have before you assume all is lost. Engines are expensive and the knowledge you gain could save you some major bucks down the road. If you want to bring it to Lakeland I would be happy to pull it apart for ya.

If the gearcase is toast then the SEI aftermarket gearcase may be a good option. You cant beat the warranty. A good used gearcase will run $400-$500 bucks or a new replacement for $795 with a 3 year warranty! OEM Replacement $2700.? You can buy a lot of fuel for a $8000. motor payment. The bigger issue is why you lost power; was she hot, fuel issue, trying to seize up, etc, etc. Maybe look at the whole issue before you go to the bank. The motor is worth the sum of its parts being an 85`.The trim system and a new gearcase are worth $1500 in pieces. Just another spin on this...

I am going to start taking it apart tomorrow doesn't sound or feel good when you turn the prop.It has a dent right on the nose cone.I can't start the motor until I atleast remove the lower unit Can't tell what the heck is going on till then.
-
There is a large roller/thrust bearing right in the nose of the gearcase that may have gotten the bang. You are going to need some stout snap ring pliers to remove the big snap ring holding the bearing carrier in place once you remove the four screws, then you should be able (with a puller) to pull the carrier, reverse gear assembly and propshaft for a closer look. The pinion gear and nut will have to be removed to gain access to the forward gear and bearing assembly.
-
I got the lower unit off and apart,the reverse gear was missing a tooth or two and the clutch dog was in parts.The price went down alittle so thats good news and I can start the motor now with a hose.I started her sunday and she ran fine for about 5 min.then it started missing this is with fresh gas.It would miss then run fine then start missing again I will start looking in to this problem next weekend any thoughts would help.
Thanks

Look for coils/wires arching to the block; a very common problem and cause for a miss. Trying running her at night for a minute and see if she lights up like a christmas tree around the coil cores. I never seen an older OMC that the coil housings didnt crack eventually and start "leaking" spark to the block. Get some insulated plastic spark plug wire puller pliers from the auto parts store and start pulling wires one at a time while she is running until you find the miss. Two things will happen; the miss will go away or the engine may actually start to run better. Keep the wire boot near the plug while doing this and you will hear the arching. If the engine runs better when you do this, chances are the plug is bad and unable to fire correctly internally until you introduce an artificial gap.
-
Thanks for the tip I will get the spark plug pullers and try that I have a coil from a motor that was being parted out if I need a replacement.
-
Did the miss start as soon as you removed the lower unit? Just a thought, but an engine will run differently when out of the water and without a lower unit. If there is less back pressure it will cause a lean condition that will cause the engine to sneeze and miss some. Before you tear into the carbs and replace a bunch of electronics, bolt it back together and see how it runs.
-
It was missing before that was part of the reason we grounded.
When I ran at night there was no arking until I pulled the plug then it would ark all over the coils on all plugs.

..I started her sunday and she ran fine for about 5 min.then it started missing this is with fresh gas.It would miss then run fine then start missing again I will start looking in to this problem next weekend any thoughts would help.

Power Packs ?
Mine ('90 150HP Mariner) did the same thing when I had one go bad. After much searching and haggling on EBay I just went and replaced power packs, stator, and voltage regulator a coupla years back. Found a "new old stock" OEM stator for $100 !!!
Anyhow, I don't have any spark / charging problems anymore.
