Greetings:<br />Last year I bought a new 04 Johnson (Bombadier) 4 stroke 60hp for my new Alumacraft Navigator. The other day I was comparing specs and noticed the Johnson weighs about 125lbs more than the 4 stroke Mercury. Seems to be quite a big difference. Does anyone know exactly why? Im wondering if I should have bought the lighter motor. I assumed they were all close to the same weight.<br />Thanks...Kevin53
