Kind of, but not exactly.
The engines were changed from 2.5's to 300's. The 300's weigh approximately 100 lbs more each than the 2.5's. So, the big pocket guys can build new boats that are 200 lbs lighter than the class has raced for years. If someone does that, then every not-new boat is automatically obsolete. It's like adding a third person to the boat.
Just raise the weight by whatever is the exact weight increase. Then, the class can continue to grow and not shrink because every not-new boat is obsolete.
The goal is to make the sport grow, not obsolete every existing team because of an engine change due to obsolescence.
They now quit making the 300 2 stroke, the V8 will probably be the next engine utilized for the class. So, the weight of the engines will increase again. So, the weight will go from approximately 370 with the 2.5, to 460 with the current 300's, to over 500 lbs with the V8 in the future.
Does somebody build a lighter boat yet in 2 or 3 years to take advantage of the new V8 when it happens? Mercury has already said they will only provide replacement powerheads for the 300's for 5 years. That leaves 4 more to go.
Or does the weight of the class increase to keep all of the boats competitive? This should be settled now. Do not make existing race boats obsolete every time an engine change is required.
