Hahaha ... dat zal kloppen Jan, ik heb namelijk exact dezelfde foto gebruikt om de maten te bepalen!

Das soll stimmen Jan, ich habe nämlich exact das selbe Foto genommen um die Masse zu errechnen!

en dan alle bij op het zelfde uit komen dan moet het wel goed zijn

Just for clarification, the motor in Jan's photo is a KG7Q, NOT a KG7H. The difference being the Q has a longer exhaust housing with an additional splash plate above the AV plate. It was used on the earliest of utilities that had 15-inch transom heights. As racers began raising the motors even higher, Mercury came out with a shorter version of the exhaust housing (referred to in literature as the Hydroshort), to lower the center of gravity by allowing the transoms to be shortened to approximately 12-inches.

Again, valuable information right from the souce, thanks!
