U J's in prop shaft

[Tranona]

Pretty certain if you had been able to post those photos earlier the advice would have been even more emphatic that you have nothing to worry about. Indeed that looks to be less than 10 degrees. Get your stern tube in solidly and then line the engine up to it. Simple.

You are right bout prop size in that you need clearance of preferably 15% diameter to the hull. However you need to get the calculation for diameter and pitch to suit your engine and gearbox ratio. The later is very important as that determines the shaft speed and therefore the optimum size of the prop.

You can do the calculations yourself using the popcalc programme on www.castlemarine.co.uk although if you are buying a new prop get your supplier to recommend the size. He will require the same information. That way if it is wrong he is responsible.

Thanks Tranona that's reassuring in itself about the angle being OK the longer I looked at it the steeper it looked just not used to seeing a working engine sat anything but level, the prop can wait till later in the yea , time to push on with the building of it just wanted to get it positioned, after spendig time and money on the engine so I can tick it off the ever growing to do list, thankyou
