Mercury 15hp Spare or repair

[luke1979]

Half way up the leg

Odd, it shouldn't have caused the impeller to break up then.


Has anyone else been near it?

[luke1979]

I Dnt think so mate I just can't understand how it's happened

[Nos4r2]

You didn't pick up a carrier bag round the prop or anything?

[luke1979]

Not far as I no mate

I have known with some cheap replacement impellers where the bonding or moulding between the rubber blades & the Centre Hub/sleeve of the impeller unbond leaving the impeller hub turning with the shaft but the rubber blades not turning or pumping water
Never seen it with a nylon hub but seen it twice with a brass hub .
Just a thought ?

[Nos4r2]

Yeah, i've seen it too-brass insert as well. Only ever on old Johnson/Evinrudes though.

Happens fairly frequently with the old jabsco impellers

I had exactly this on our old 5hp Johnson 2 weeks ago! Luckily I noticed the lack of telltale as soon as we left the pontoon, so put the boat straight back alongside. The impeller hadn't been changed for at least 3-4 years (possibly more), and the rubber blades had completely separated from the brass hub.

i managed to pick up a 15 mariner for £400

however i had a 10 merc before this and ended up buying another engine to canabalise the parts. it cost a small fortune to have it sorted carbs setting ,coils not firing etc . by the time it was finished it was mint

if i could it again i would have scrapped the first engine as it cost around the £600 mark but i half enjoyed the learning curve

[paddlers]

So what emerges is that cheap impellors might fail but genuine spares shouldn't ? I'm always looking at the tell tale but have always been reasonably confident that if it's been replaced with a new one it should be fit for purpose.
Bit of a worry when you think of the cost if one fails. The only time that I've ever shut down was when my old 85 Yam started spluttering with no tell tale........... turned out to be the pipe separating under the hood & soaking the electrics but it did cause initial panic !

That is wot my engine needs

The labour part seems very low at £90. I suspect the final bill if you have it repaired will end up much higher.

I would be tempted to sell the engine for spares, and start again with a different engine.

Why would u sell engine what is wrong with gettin it fixed

as you seem to be on a tight budget, and who isn't these days, I think I would go for getting the engine rebuilt, as long as you can get them to agree to not going over the quote without talking to you first

[luke1979]

It should b 150 but cos they no a have nt much cash so charge me 90pound

I would be worried that getting it repaired may end up more expensive than selling it for spares and then buying a replacement. Repairs often end up costing more than the original estimate due to unexpected problems.

[luke1979]

Why would it they have told me the price and it won't b goin up that is final price

I'm just saying be careful and ensure that it's clear who takes the hit if the repair takes more labour time or needs additional parts.
