This ski boat was brought to us after another repair was found to be not quite up to par and therefore some rot has encroached into the aft keel section. We will be removing several bottom plank sections and part of the keel in order to repair this area.
Powered by a GM 283 with 185 hp, plenty to pull skiers with or just run the lake!!
Above photo shows the rot in the keel area and my finger gives you an idea how deep it goes. Approx. 11/2 inch.
The above two pics show the same area and allows a different viewpoint.
Here we have the rudder shaft and packing gland tube. Notice the area around the tube and one of the carriage bolts. This dimple show soft areas in the, also just below is the start of the open gouge shown in above photos. wood which is rot
Above two views... left shows planned area to be removed looking at it from the bottom. The right is a view from inside showing the area to be removed to access the bottom planks to repair.
Pic of the right trailer wheel and hub, which was smoking when arriving at Woodies. We will be removing and inspecting this to see what needs to be repaired. Suspect as a minimum the wheel bearings.

old keel removed
transom bottom middle, rot where keel connects, arrow 1 is transom, arrow 2 hole in bottom plank of transom
looking up at transom center support beam, rot appx 4 inches deep up into beam
transom bow from bottom showing pic wstuck in and the hilt is even with the bottom planks, arrow 1 shows bottom planks, arrow 2 shows aft planks and hilt height
keel removed, plank to stbd showing rot. Arrow A shows 5200 sealant and as we see rows of it instead of solid spread layer. This is the culprit of your rot. B shows an edge of board whic was rotted alsodue to water and mold spore groth.
from inside boat, stbd plank by keel shows a lot of rot
transom bow rot under lifting ring support, also shown is rot in bottom plank of transom, looking from underneath facing aft
close view of transom bow rot, screw shown was for the keel but not holding anything. Arrow 1 shows transom bow good area, arrow 2 shows planks on back of boat.
view of rot in transom bow from directly underneath, rot is appx 3/4 way thru bow and approx 5 inches wide
hole in 1/4 ply port side
another hole in port 1/4 ply
The decay in the transom bow is approximately 3/4 way into the bow and about 5 inches wide. Also bottom transom plank has rot in middle area about 5 inches across and 2 inches high. All rotted keel removed and side adjoining planks inside hull were removed also, support plank running across for the shaft support strut was removed due to rot.. The keel will be replaced with a specifically cut piece and other internal planks will also be cut to fit and replaced. This rot was caused by, as we see it, improper application of the 5200 sealant between the layers of wood and seams. Should be applied in a solid spread layerr with groves to allow boards to squeeze the 5200 flat and cover all voids and spread out thru the joints between boards. Without this the water has channels to follow and sit in which allows mold spores to grow like a cancer slowly eating away the wood.

Above is transom showing rot in bottom plank which is attached to a support beam(transom bow), which holds stern together and is bent with steam for strength. We will have to remove this bottom plank and then the transom bow. this will take 1 to 1 1/2 days. Then we will replace these which will be another day, day and a half. After we will reinstall keel and all associated bottom planking which will be a day and a half. This gets us to 5 days, then we will sand prep cepes and paint. Actually it is a little more involved than just described but it gives you a good idea of the extent of the work. We do not expect to find any more rot as we have wlooked it over carefully. The 2 pics to the left show the transom bow from a bottom view with my finger in the hole and as you see it is 2 1/2 inches deep into the wood. "actual length of finger from tip to middle nuckle".

shaft log removed to plug and redrill all holes and seal with 5200 due to stripped screws and seeping leak.
old shaft log removed and cleaned ready to reinstall
5/27/10 We took boat to lake to dip test and ensure everything was ok. New repair was as expected, "No Leaks". Now I saw water seeping from the rudder log and the shaft log. Tightened rudder packing gland and stopped that leak. Tried to tighten shaft log packing gland but found water was coming from around the shaft log itself. After discussion with Jack and Paul, I removed the shaft log and cleaned area and log. I then plugged old holes and will redrill when glue sets and apply 5200 to log and boat and no more worries. I also painted around entire boat bottom edge and under the bow to blend bottom in with aft repair for cosmetic appearances.
Shaft log replaced, note 5200 seepage
Gas tank back in place
