None... Both are totally different things... HP is for an engine, PSI is for like tires
110 - 130 Scfn is what in psi
I have a 2005 and compression should be close to 120 psi. Normally a good engine will have compression between 115 and 130 psi but a leak down test should be performed also to know the full condition of a cylinder.
The total head will determine the psi.
100 psi to 140 psi.
In the yesteryears of outboards, compression readings of 150 - 180 lbs were common. Today, for 2 stroke models, readings of 110 - 130 are average. Basicly, anything over 100 psi is good, with no more than 15 psi variance between the highest, and the lowest cylinder readings.
At 300 feet of water depth the pressure is about 130 psi
HP is not determined by PSI.
60 psi at normal max working psi, the keg is designed to hold 130 psi before the safety valve/release will kick in to release the excess pressure. P.E.T plastic bottles (soda) are about the same 130 max before BOOM.
About 130 psi at 300 feet of water depth.
The 1992 model, 25 hp Evinrude outboard will usually run between 120-140 psi. The main thing here is that there is no more than 10 psi difference between cylinder readings.
Around 130 hp
Cut out pressure is between 115 and 130 psi... cut in pressure is no more than 25 psi below the cut out pressure.
