A friend of mine had a leak he couldn't find on a 17' spectrum.  It ended up being a crack in the hull that was mostly obscured by the bunk. Pressure from the bunk pushed along a hull stringer over time and created a crack.   The way it sat on the trailer it didn't really leak when he filled the hull with water (not the same pressure inside to out as when it was floating and outside to in.    

That's interesting.  This time when filling ith water I will be jacking it a bit off the trailer bunks, especially when tipping side to side.

One thing here has not been mentioned yet. The bilge pump hose outllet. It may happen that the hose coming from the pump to the drain hole in the side of the boat sort of hangs down. This allows wave action to throw small amounts of water into the bilge pump and into the bilge from there. The easy fix is making sure that the bilge hose is kept higher than the bilge hose outlet so the water cannot get in. Don't ask me how I know this.

Bilge hose discharge is very high above waterline.  As for the livewell/fishbox fill pump, it is in the transom below the waterline.  I have plugged it an ran a while like that. I dont use it much anyway.  No difference, still leaks.  Keep in mind, leaks the same amount weather sitting at the dock or out fishing.

I will pull it from the water after next week. Let it set for a week so the outside is dry.  Fill it with water and food coloring.  Tip it severely so all water moves to rear, wait a few hours tha tip to move water to bow, wait than tip side to side.  Maybe I'll see something that way.  Not at the camp now but will be monday.  Will take pics of inside.  Removing the gas tank is not a big deal because it has it's own screwed down cover. I have had it off before to replace the sending unit.  Yes, I do troll with the 70 and use the electric motor on the bow for autopilot. 

The shame of it is that it has an aluminum floor so I had never planned to pull it up.  If necessary to do a proper Gluvit job I will.  Probably will pull the gas tank first to get a view of some of the hull.  The gas tank has it's own removable, screwed in floor and takes up a considerable amount of the cockpit area. Pull the tank and run it from a 5 gal tank, put it in the water and see what developes.

Check the seam between the inside of your transom and the transom splashwell. Before i repowered and replaced my transom and resealed that seam on my Sea Nymph it leaked like a sieve anytime i used the boat and waves or rain washed into the splashwell.  Even when your boat is tied up any movement of the transom in wind or waves can cause the transom to dip low enough for the splashwell drain holes to take on water and if the seam between the transom and splashwell is not water tight, water will leak into the boat. Seal it with 3M 5200 and you should be good to go, if thats not the issue, back to square one. The transom rotting and pulling away from the splashwell was the cause of my issues by the way, may want to take a look at yours if thats what it turns out to be. Good luck!

 

Here is a link to a post from my Sea Nymph repower and transom repair which may help explain what i'm talking about. 

 

 

This leaks just sitting at the dock when the water is well below the splashwell.

Make sure your speed gauge tube is hooked up and not flopping around.  I had one become disconnected and it pumped water into the boat anytime it was running hard

That was happening many years ago.  Got rid of the pickup and tube.  Just use gps speed now.

Am I right to think that you went from a 2 stroke to a 4 stroke with the same or maybe even higher horse  power? If so, the much heavier 4 stroke will have done a job on your rig and this leak which is probably on a seam is only the beginning of more trouble to come.

Went from a 115 Johnson to a 2014 Yamaha F70LA.  It is enough power and gets great milage.  Johnson was about 290 lbs.  F70 is 257 lbs.  Lighter than most 70   2 strokes.

Discharge from the fish boxes is up front and about 4 inches above waterline so it wouldn't be that. I plugged the intake in the transom but was no help. This is a GLS 175 which is different than the GLS 195 in that area.  Going to look into Rolmops idea.

Since it started after you replaced the motor - look at the sealant around the bolts that penetrate the transom that mount the outboard to the hull.  Maybe even pull one at a time and re-bed with 4200 of those are under the water line. What about transducer screws?   Those are sometimes a good source of leaks as well.  

Lower motor bolts are below water line and were well below where I filled the boat with water. Had it filled for a few hours and nothing came out there.  You can also see the bolts and nuts when looking in the bilge, nothing apparent coming in there.  When the boat was filled nothing came out sny transducer mounts, fittings , etc.  I guess it may be a good idea to reseal everything anyway.

I have a 1993 Sea Nymph GLS 175 that I use for early spring browns, bass, walleye etc.  Put a new Yamaha 4 stroke on in 2014.  It has developed a significant leak late last season. Takes on about a gal an hour.  I pulled the boat, let it on the trailer for a week to let it dry out inside and out. Put the plug in and disconnected the battery to kill automatic bilge pump.  Filled it with water nearly to floor level which is above water line. Had one small leak at a rivet, about 6 drops a minute.  Replaced it with a closed end rivet and 3m 5200.  I have replaced a few rivets in the past few years.  Filled again a day later, all good.  Put back in water, still leaking at the dock. Plugged the intake for the live well pump in the transom just in case that or the hoses were leaking. Still leaking.  Live well drains are out the sides and about 4 inches above the water line so it wouldn't be there. No apparent leaks visible from inside the boat in the visible bilge area.

Totally stumped at this point.  Any suggestions ??

Comorants!!

May get more response if u mention make, model, year, etc.

5 so far this morn.  Two had double lampreys.  One had a single lamprey.  Crazy.

Caught 6 cookie cutter browns in front of Sandy Pond yesterday morn. All had lampreys on them.  Worst I have ever seen.

Found this canvas about 1 mile north of th Salmon river on Rt 3.

Looks like a cover for a small boat

But unsure.  Message me if it is yours

I had a 1987 Fishmaster. I believe it was 22 or 23 ft.  Send your phone # as a private message and I will call. I can point u in the direction of things to look for.

On second look, there is probably a brake fluid reservoir under the plastic cap .  The fact that the pin with retaining rings is in a slot is a definite sign that it slides to actuate. I have just never seen one like that in 55 yrs of boating experience.

Don't see any signs of surge brakes.  See other issues with setup.  You should cross the chains so that the tongue has something to land on before it hits the ground if the hitch detaches.  Also, it seems the chains are attached way, way too far back and are too close to the ground, possibly dragging.  Even if they were crossed it wouldn't help.

I fish the east end also from Sandy pond to Mexico area.  If it is a westerly wind and u are willing to take a bit of rough water to get there, the Catfish creek area offers some protection.  Doesn't help with NW, N etc winds.  I use a 17 1/2 Sea Nymph for Spring Browns.  If all else fails, u can trailer to Oswego and fish the harbor.

Out of Mexico?

Cool! I wonder if anyone checks on launches regularly. I recall last year with the super high water many were posting updates

Must have your years mixed up.  Last year was terribly low.

I will take em.  Check your private messages.

Any info on the Mexico Launch would be appreciated.

New prop still in box.  Never used. OMC part # 386786.  12 1/4 ×15.  

$65 +shipping or pick up in Mexico area on my next trip in the spring.

Don't know your location but Schermerhorn Marina in the Thousand Island area did an excellent job on my trolling motor when no one else wanted to bother.
