Hi - I have two questions, I have what I believe to be a 1962/63 40 HP Johnson on a 14 foot Polaris V-hull.<br /><br />1. Can you confirm the details on the Johnson?<br />Model RKL-25D<br />Serial # 0390346<br /><br />2. The Polaris hull is rated for a 40 HP engine, is this a weight rating or a speed rating. The current engine may need to be replaced and I am curious if I am able to put a newer, more powerful engine (i.e 60 HP or more)<br /><br />Thanks kindly!
