How to find the HP of your engine?

[Ex Brummie]

If you look at the last licensing form, it is usually stated on there. My Perkins 4108M is rated at 28bhp, as being governed to 2,100 rpm, it will not reach the sort of ratings stated/achieved by many of the marinised conversions that will still rev to 4,200 rpm. At 28 bhp, it still has more than enough capacity to tow another boat on the odd occasions it has been needed.

. On his second resit he said he would stand the barometer near the base of the building and use the length of the shadows to calculate the height. Eventullaythe examiner gave in and passed him.

Remember doing something like that with a foot ruler when I was at school, measure how far from the building you are and sighting the top of the ruler to the roof and the bottom to the ground and working it out.

A proper engine has 'Made in Japan' on it and needs looking at so rarely that I've forgotten where it is!

 

 

Nah - painted red and made in Denmark for real marine use, not some ponced up mower engine.

Reminds me of a student who failed his physics exam. The question he failed was, 'how do you measure the height of a building using a barometer'? He thought this was daft so he wrote that he would drop the barometer off the top and time how long it took to hit the ground. At his resit he said he would use the barometer like a yardstick and measure the inside wall as he climbed the stairs. On his second resit he said he would stand the barometer near the base of the building and use the length of the shadows to calculate the height. Eventullaythe examiner gave in and passed him.

Like that, have a greenie!

Thanks!  you can set yourself the puzzle of adding more methods for answering the question without using pressure.  For example, tie a long piece of string to the barometer and suspend it from the top.  Give it a swing and time the oscillations.  It can become quite a shaggy dog.
