Some tech questions Mercury T2 ??

[Droll-l6]

Got a Mercury T2 that's going tru a looong term restoration, slow progress at the moment but it's going forward...
Got 99.5 % ft the part's needed but I got some questions..



Planed to use some 2-ring high dome power port pistons from Sierra but after reading a post at this forum some older concerns came up again.

Will the hole in a power port piston come in conflict with the center port on the T2 ?? , will of coarse work but with the lack of some power ? or ?

Tracked down some NOS Merc #9137A13 ( + .015" ) pistons just i case as they might be better performance wise ?.



Question #2
Got some NOS reeds for the T2, lately I have spotted some new reeds available for the engine ( CCMS ), would it be a good idea to purchase some new reeds for the engine ?.
Those NOS reeds I got are probably 30 years ++ old , unused but old ...
