You may be asking, “Why should I invest in a Shaver-Wesmar Gear Drive?”. Simple. Ron Shaver and Bob Westphal have combined over 70 years experience in the engine building business - these gear drives are built by professionals. They are used on all Shaver and Wesmar engines. Every time a Shaver or a Wesmar engine comes in for a rebuild, they are there first hand to examine the gear drive to see if anything is at fault, or if there is something they can do to make an already great gear drive better!
