Finally got to this job, it's only been three months. I needed to acess the pick up tubes in my forward tanks in order to run new lines and a second separator/filter. A few monts ago you guys talked me into the armstrongs and Capt. Chuck generously sold me some from his inventory.
After plenty of measuring, some of which started last year, I decided on a test hole of 2" to get me in the ball park then fine tuned the placement after I knew excactly where the fitting was.
Then I used my handy Rotozip with the circle atachment to cut some 7" holes in a deck that I redid only 3 years ago.
Hard making the first incision into a completed project. But all is well and they should work out fine. Check out the pics.
Finally here is the objective. Access. The tanks are made by Sunrise marine and the stamps say 58 gallons and have a date stamp of 1982. The hull is registered as an 86' and I was told the 4 tanks are 50 gallons each with a total capacity of 200 gallons, I wonder if the back ones are smaller. Anyone know Whitewaters or Sunrise marine? Other Tom if you are out there what were your old tanks like in your 25?
In the future I may try flush mounting these like Capt. Chuck posted but for now I need to get this boat WET!
Thanks eveyone for all the help.
