1. Use the full 4 digit year for everything you are asking your question about. Example: 1962, 1988, 2000, 2011
2. Include the correct name of your Whaler model. Example: Montauk 17, Montauk 170, Outrage 26, Outrage 260
3. Include the length when necessary. Example: 16, 17, 18, 20, 22
4. Do not post your email address anywhere on this site as it is already in your user profile.

Drilling holes in the hull to determine if water is inside..

It is a banana hull, 22 ft early 70s style Whaler. It has become heavier and noticibly needing more power to haul loads. I figure before I tear or ATTEMPT to tear the floor and foam out I should drill a few holes first. So please give me some advice and maybe exactly where to drill and how big and deep. Thanks.

Are there any repairs on the hull, deck, gunnel, transom? I take it, based on your location, there is not a weight scale close by to weigh the boat and trailer. I'll let the pro's comment further. 1992 Outrage 17 I 2019 E-TEC 90, Viper 17 2+ 2018 Load Rite Elite 18280096VT

My 1990 Revenge has water inside the hull and I've convinced myself that I'll never get it 100% dry. I have two 1/4" holes drilled in the hull. Both are within 3 inches of the keel. One is located forward 12', the other is 2' forward of the transom. I have tried a handful of methods to remove the water. I've tried 20-30psi of compressed air for short periods of time. This method never produced alot of water. The holes have been there since last September. On sunny days as the hull warms in the sun, the water will start to drip. I'll get a slow drip for a few hours. The puddles never gets any larger than 5-6 inches. It is salt water, however, the boat has not seen salt water since last August. I have been busy using my Conquest this spring, so I've been able to leave the drain holes open while I continue to slowly restore her. The thru hull tubes were rotten when I purchased the boat. I believe that's where the majority of water came from. I am covinced that the foam that Whaler used will most definatley trap water. And as some of these hulls go through freeze thaw cycles some of the closed cells in the foam are broken open allowing them to trap larger volumes of water. Not to worry, I still believe there is no better or safer vessel on the water. Best of luck, Norm

I also agree the thaw and freeze cycles affect the water/foam trapping, especially living here in the Arctic, freeze means FREEZE. I think I will drill holes here and there in the hull, maybe 3/8", 2 to 3 feet apart I figure. I believe there are cells and I need to guess where and try to miss them so I drill where the water may be. I believe I am correct to say that there is NOT a fuel tank on my model, so thats reassuring. I think during the LONG winter I will tear the floor and foam out to really take a look and see for sure. Now I need to get ready for salmon season, drilling holes sounds an easier job. Anyboby else has any ideas or procedures I appreciate. Thanks for the welcome too. Darin

Whaler also offers a pvc drain tube. 1963 13' Sport 50hp Evinrude Maintaining a level of sanity that is socially acceptable
