Towing Load on Engine
I'm trying to figure something out...what puts more strain on the engine?
Towing, or hard riding? For example:
Offshore riding: 60+ MPH, 7000+ RPM, 75-100% boost.
Towing a skier: 18-20MPH, 4000-4500 RPM, 0-5% boost
I think the engine is under more strain from offshore riding, but many people are telling me that towing puts more strain on the engine. What is correct? With a boat, water is always loading the engine, I would assume the less RPM the engine is turning, the less of a load...

2 different types of load
offshore riding gives shock loading
towing gives continuios load on engine etc
all depends what you are trying to find out with this question ?

I onced towed this canoe for about 15 miles when the wind died. I was just a safety boat running with them that day. Was going about 10 to 15 mph, 4000 to 5000 rpm no problems

Just curious for my own knowledge...
I'm familiar with automobile engines, but I love the water and want to get more familiar with marine engines and how they work.

I've towed a 190 lb man on a large tube behind my 15F at WOT for miles and still hit my normal max rpm.
Done this a lot. Everything was fine with it.

be careful if towing with the solas 16/21, rapid decelleration with a heavy towing load from moderate speed can spin your impeller off. (eg a wake boarder)
