Yamaha has a variety of outboard engines ranging from as little as 2.5 hp up to a V8 450 hp motor. The individual product pages give all the info you need ranging from weight, RPM range to the fuel induction system, and what engine oil is recommended. You’ll also see want to note the warranty your motor has, which is important in case you need to head in for repairs. If you’re trying to figure out what gauges and controls are compatible with the motor, you can find those on the product page as well.
Your tiny boat doesn’t need a 450 hp engine, so don’t go out and buy the biggest and strongest engine just because you have the budget. Instead, you’ll need to look more into what you need specifically. You can do this easily by knowing the weight of your boat. Typically, every 25 to 40 pounds of weight equates to one horsepower needed. While a lot of people equate hp with speed, it’s needed to get heavier vehicles moving too.
The engines are broken up into the following categories — Jet Drive/High Thrust, V Max Sho, 2.5-25 hp, 30-115 hp, 150-350 hp, and XTO Offshore. The XTO is a V8 engine while the V Max Sho and 225 hp and higher engines are V6s.
