What do you expect from your engineer

I call myself engineer.

Qualified CAA avionic design signatory, unqualified boat tinkerer.

When I did my boat thing, I was technicianing but called myself an engineer, cos I am :)


You can do some types of shaft seal in the water (stuffing box style - I've done it) but be prepared to get wet. And maybe a bit scared for a few minutes...

One "non engineer" even changed a seacock afloat with only a pint or two coming into the boat ;):encouragement:
 
When I employ someone to do work on my boat, I want them capable and experienced. I work with many Engineers, and have done all my working life, few of which I would want anywhere near the mechanical bits on my boat, albeit they are all excellent at their jobs, none of whom are boaty technicians.

For me this is not a snobby bit, this is all about having the right people to do the right thing. I have found that chatting to others in any Marina will point you in the right direction of good people. Word of mouth generates the best credentials.
 
ok guys i have the engines and fuel sorted ,to be done by engineer ,but seems they just change oil ,filter and check belts ,but will be there next time to see ? toilet and holding tank can sort my self ,yes stopped the swimbo using wipes .ok i dont think there is a sea cock engineer ,may be an engineer who is a cock ! .So i need to what to do or to make sure they know ,steering is pumped by each steering wheel i found that out when went through the swellies without steering ,just using engines sh iit, its the shafts that scare me the most ,omega shows a photo of boat out of water is that the cutlas bearing and is the stern gland in the hold so when should each one be checked or changed and if you dont know when they where last done should you do it as and when .sorry so sounding thick but been empying you bins since 4.
 
Seastoke, many thanks for emptying the bin this morning, you travelled a long way to do mine, but much appreciated :)

The cutlas bearing is the one on the "P" bracket, below the hull, that supports the shaft just in front of the propellor. The gland will be within the hull, and seals the prop shaft through the hull. Depending on the type and make of gland, it will either need constant checking, or periodic, but I suggest you take a picture and post on here, so folk can make a more educated stab.

There are a variety of different cutlass bearings, but I doubt if any are ball races. If you post your boat make, then it is likely that someone on here will know the type of bearing.
 
A full description of your boat would help a great deal, as already stated there are many different ways of shaft sealing, but the bronze tube in my photo is the cutless bearing, remove prop, remove woodruff key, remove grub screw, then with a drift knock out the old bearing, we use a 8inch piece of scaffold pipe cut down the middle that sits on the shaft and slides into the P bracket, however a "Techie" would no doubt have a suitable puller. Before you start tearing things apart though, grab the prop and see how much up/down, and side to side play there is.

hi omega right the boat is i colvic 36 fly twin on shafts it was re engined with tow perkins sabre 225 turbo,s it had new shafts and props ,all before i bought it so dont know what type of seal or bearing but i have no vibration off the engines .i am just trying to put a check list together when she come out in march,but is it normal to service the engines when in the water , yes i mean the boat ,

Engine servicing is best done with the boat in the water. You really need to get the engines warm before sucking out the engine oil, as it is much thinner when warm, and with a shaft drive boat it is not so easy to get cooling water to the engine, and you do not want to run the engines without coolant. Sorry if I am teaching grandmothers to suck eggs, but am not sure of your tech knowledge. You use a vacuum oil sucker from Pela or similar, about £40 for a 7 litre version. The oil is withdrawn from the dipstick tube. It takes a while to drain fully, so it is a job best done by yourself rather than a technician, as it is not difficult. Oil filters are usually very easy to change too, but you will need to check if they need priming (filling) before mounting.
Good luck.
 
simlar but we have the stainless radar arch she is a 1990 engines have done nearly 200 hours ,all new electrics with new chargers all new holding tank toilets and pipes new pimp out pump the steering is old the steering wheels create the pump to do the steering i always steer from the fly ,new bow thruster
 
yes thanks for that ,ok engine cooling does it suck sea water through the sea cocks and back out of exaurst
 
s new pimp out pump the steering is old the steering wheels i always steer from the fly ,new bow thruster
Pimp out the bow thruster!!:p
He has to steer from the Fly Folks
You canna see owt from the inside-- too many instruments, m ostly old stuff from the previous owner who really pimped his ride
But no friggen compass would you believe!! never mind the old steering wheel!:rolleyes:
seastoke-- I will fetch yer man I was talking about when you lift out if yer like
We can talk you through yer shafts etc etc etc
