that type of engine solely depends on the person on it. With the average man on it (180ib) or bigger than you are looking at 50-80 mph 180-190=70 -80mph for every 5 pounds bigger take away 5 pounds
Not very fast, possibly about 25 mph.
Not very fast at all because of all of the weight but the 150 pounds would almost even it out.
On a valve-in-block 8HP with an RJ19LM or equivalent plug, it is 0.030"
Briggs straitton
It is around a 5 hp. *this is incorrect: the ones they sell currently would be more in the 7.5-8hp range, seeing as an equally featured 190cc briggs and stratton engine is 6.75hp on a lawn mower the additional 15cc bump it up to around 8hp.
10 15 mph depend on size of boat
Depends if you put it on an 8 foot skiff or a 40 foot barge.
For an 8hp Briggs & Stratton engine, it is recommended to use SAE 30 weight oil for warmer temperatures and 5W-30 for colder conditions. Always check the owner’s manual for specific oil recommendations, as some models may have unique requirements. Ensure the oil meets the API service classification for small engines. Regular oil changes will help maintain engine performance and longevity.
Capacity is 36 ounces. I highly recommend you use Synthetic oil in this air cooled engine. Change it once each year.
