Re: What should a Noob not tackle??
You really can't compare boat to car motors. Cars can coast. Cars have gears, so at 55 mph, you are in high gear and the car motor is at about 1500 rpm.
A boat motor has to either lift almost the entire boat out of the water while on plane, or push all that water out of the way. Either way, a boat motor is at higher rpms all the time. Boats don't coast. It's like your car driving up a mountain, towing something, ALL THE TIME.
The plus side is that outboards are built much better and are much better designed than most car motors. Many 40+year old outboards are running just fine. One thing that hurts outboards is idling around too much and driving too slowly. Outboards need to be driven at wide-open-throttle (WOT) often to blow out the soot.
You would think that boat motors would run forever. They don't get used as much as cars so the hrs should be low compared to a vehicle of the same age. I don't know what makes an outboard tick, but it seems like unless you boat year 'round (that must be nice) it would be easy to maintain one for a long time.
