Hello Pete

It's 1991 so it's only 20 years old. Plenty of life in it yet!

Your welcome

A bit of both I guess in all honesty. I've had some that were dead at that age and others that look better than newer models. That can be said for any make though!!!

Getting off the fence though dependant on the price I'd say you will be happy with your purchase. It's already standing the test of time so based on regular services and the usual maintenance (flushing after use etc) I'm sure it will serve you well. Enjoy!

Hi

I have 75hp mariner year 1987 and run like a dream . Start first turn of key all time .

secondopsman · 06 October 2011, 20:49

Well it seems i should have listened to my old dad and done some research before buying anything.I started of by buying the boat whilst on holiday (spur of the moment thing)Pheonix psd110 with a 15hp Suzuki long shaft engine.Then i found that the engine was incorrect and should be a short shaft.Then a freind at work whos father in law was ill mentioned he had a short shaft for sale so i just bought it.The mariner 30m.Now i have just found out that the boat should have a plate on it and it hasnt and the max engine size is 20hp.

I have weighed the engine and its only 5 kg heavier than the suzuki and i have no intention of running around flat out.
Do you think its wise to use this engine or should i throw the towel in now

Pete

Use the engine . Transom will take weight of engine and always nice to have extra bit of power wen needed .

I am thinking that way to be honest.

FYI the engine is an early Mariner made by Yamaha. The year of manufacture is 1984. Good basic engine, if it runs OK I would use it.

Ohh conflicting. Can I ask where you got that from ? The quick check I did put it at 1991. Am I wrong ? Here's the info i got on it which shows the Mariner 30M with that serial range (right at the bottom of the picture). The 1984 models were 30A M with serial range of 023****

Or am I reading it wrong ?

I use a different source to you Peter and that gives 1991. I think Aqua has made a mistake on the serial number range by a factor of 10... easy to do when scanning down the years.

aquatec · 11 October 2011, 18:45

Yes guys you are correct, I got it wrong with the zero. Sorry about that.

I expected it to be the 30hp Yamaha Origin series too. A good enough motor. When you rev them without load they knock and pop alarmingly as the revs drop. It's not a fault, that's just what they do. 50:1 oil on the Mariner engine. 100:1 on the Yamaha, hehe, you choose. They were used by the RNLI at that time.

75/1 seems reasonable compromise
