Default 4hp Vs 5hp Ottawa Drag Saw

I bought a Ottawa log saw at auction last weekend, it's rough but fairly complete. The saw mechanism is free and I can turn it using a monkey wrench on the large hex nut.

It's a 4 hp with a serial number TE9981.

Most of these that I have seen were a 5hp but look pretty much the same as this one. Are there any differences between the 4 hp and the 5hp? Did they just up the working Rpm rating?

I have read a little bit about them. Guessing this would have been built in the mid to late 20s. Did make both 4 and 5 hp engines at the same time or did the 5 hp replace the 4?

There are differences. I have a 4 horse with two flywheels and a different mag than my 5 horse Ottawa which has one flywheel.

I have both and cut with both at the Rough & Tumble reunion this year. The 5hp cuts at a slower speed, I guess due to more torque. The only difference that I have found is the piston diameter. Found it's better to cut slow, we're doing demonstrations, not feeding the mill. They tend to be kind of violent at speed, make sure it's chained good. We made cribbing from railroad ties to secure the logs. The bigger the log, the better, gives em something to chew on. Mine are single flywheel. The clubs 2horse Whitt is a much nicer saw to operate, if I had to do it again I would rather have one of them. Good luck and be safe!

BigGoomba , could you tell what it is that dates your saw with serial number 9981 to the mid to late 20’s ? I have two / one with the number 8287 and the other 10028. Also do you have anymore pictures of saw in the attached photo in your above post? Thanks. Mike

My son had a 4 HP, single flywheel. It sure was a bouncy rig! Try to cut anything under 6" in diameter, and it would spin in circles! I had a headless witte, 2 HP rig, and it hardly ever moved!
