Locating New Engine Mount (A-Frame) Bolt Holes

[rdc54yty]

Boat is 1987 Sea Ray 19' Seville CC, 3.0L Merc, Alpha 1 drive. <br /><br />I'm having the engine mount former replaced. I'd like an accurate method of locating the new mounting bolt holes. Will measuring equal diagonals from the stern plate mounting lugs be sufficiently accurate? And should the interior of the new mount holes be somehow sealed to prevent future water infiltration? <br /><br />Also, could someone describe or reference a detailed procedure for realigning the engine? The Merc manual lacks the detail I'd like (shade tree mechaninc, you know) to feel sure I can do it correctly.<br /><br />Finally, can some one tell me how to get a topic deleted. I first posted this in another forum then wanted to move it but moving/deleting was disabled. Couldn't figure out how to contact the mods either.<br /><br />Thanks in advance,<br />Keith

Keith, right and left are pretty much aligned by the rear mounts, at least good enough to drill thw mounting holes, before drilling take the weight off the mount and let it center it's self before drilling. You will need a alignment tool to do the up and down, they are kind of pricey so if you can't borrow one let a serviceman do it---Bob

Absolutely Keith. The best way would be to get some CPES, from the Rot Doc:<br /><br /> http://www.rotdoctor.com/house/Hsealer.html <br /><br />Pre-thread your lag bolts into the new holes then mix and pour CPES into them till they quit absorbing it. <br /><br />If the new mount timbers have not been installed yet, I would pretreat the whole exterior of them with the CPES as well, pay close attention to allowing the endgrains to absorb as much as they will.
