late entry to the world of stink pots

[Chae_73]

Afternoon all.

After many years as a raggie, I am now part owner of a very minor motor boat. It is hardly enough to justify posting here, but I thought I would anyway

We have an 18' Plymouth Pilot type harbour launch. I don't think it actually is a Plymouth Pilot, but it's certainly quite similar. The bloke who we bought it off had no idea what it was, seems like he ended up with it on the back of some kind of part exchange or debt fulfilment .

It has a VP 2003 3 cylinder thing. A bit noisy but goes ok. Initial "sea trials" show that full throttle produces just under 2,300 rpm which seems on the low side - over propped? And if so, does this matter? At full throttle it is nose up and doing its best to get past hull speed so I doubt it's going to go much faster.

thanks in advance for any thoughts.

Welcome to the World of stinkpots, many ex-raggies here, and most are not so bad.

If your motor boat stinks, there is something wrong with it.

To my mind, if it is reaching hull speed in a displacement boat without the engine working too hard, Happy Days. Keep the revs down, keep the noise down, keep the wear down and save fuel.

It gets to hull speed at around 1,,500 -1,600 rmp in calm water, with 3 people and a large dog in it.

Overpowered - really needs only 20hp, so has been overpropped. However it has been working for 30 odd years like that so just carry on. Our club workboats are Pilot 18s with 30hp engines so they can be used to move boats around the marina and carry up to 6 passengers out to the moorings. Joy to see experts move 40' boats in and out of berths using the workboat as a tug with precision!

That sounds good to me. I'm guessing from pics it's not designed for fast planing so I'd be happy with her chugging along at 1500-1600. She'll probably do that forever.

. You will never get a gin palace , unless you 3 people and swimbo.

The dog's in charge and has given it the thumbs up
