Hi everyone,
I recently bought an 8m old fishers boat for cruising the canals of Amsterdam. It's a side project and I have enjoyed working on install a new dashboard and installing an alternator in order to charge the battery.
Installing the Alternator required creating a bracket that holds the alternator in place and creating a custom pulley to drive the alternator from the crank shaft. This works nicely and I'm pretty happy with the result, installing a volt and Ammeter in the dashboard to see the charge / discharge of the alternator / battery.
Next step is to install more instruments to measure the oil pressure and temperature. The question is how to place the sensors?
Engine typeOr actually maybe the first question is - what type of engine is this?
Here are some images:

How / Where to install the pressure / temp sensorsHowever what I'm now trying to do is figure out where to put the sensors for the oil pressure and a temperature meter.
I've found this existing bolt that feeds and existing mechanical oil pressure meter (I will be replacing this one with an electrical one):
Threading of this boltThe outside diameter of the thread is 13.2mm and the inside 11.4 which would lead me to believe it is UNF 1/2-20.
Of course my oil pressure sensor has a 1/8 NPTF thread. As well as a temp sensor would.
I could find a converter bolt that fits the thread in the engine and an NPTF on the other side.
Another interesting thing is that this bolt revealed an inner pressure tube similar to the tube connecting to the oil pressure meter. Can I safely ignore this tube and leave it dangling in the engine?

Open questions:
- Can anyone identify this engine quickly / instantly / easily? (I think it's an SR3M myself but unsure)
- Am I putting the oil pressure sensor at the right place?
- What kind of bolt is that? Is it indeed an R1/2 - 20 UNF bolt?
- What's the function and significance of the inner tube on the inside of the engine?
- Will a connector like this

Any comments or help greatly appreciated!!
