Mariner Vs Optimax differences anyone?

Courageous · 08 June 2011, 19:16

Hi guys, I have a very poorly 150 Mariner EFI year 2004. Its been run with no oil and alarm ignored so we have 6 low compressions and the reason for one is that the conrod has snapped. Been mulling over what to do, strip to evaluate repair, break for parts to sell or finally wait for a suitable recipient engine of the useful components.

On the bay of fleas as we speak is a similar age Optimax 150 which has been submerged (apparently) for a brief period of 2 hours.

Notwithstanding any corrosion which may have taken hold I was wondering whether the most vulnerable parts from my donor motor (the electrical components) might be compatible?

Can anyone please help with certainty?

Thanx guys.

Two different motors althought both two strokes Opti's are far different.

as said above both completely differant obms, any obm that has been under sea water i would be very sceptical about if ALL the electrics havent been replaced

Ok guys thanx for that. Al, I would have hoped to replace them all but not at the prices these parts are likely to cost. Time to steer clear.

Thanx again.

Personally I wouldn't touch a submerged opti.

If you insisted on having a go at it, all of the electrics should be replaced and the oil system would need to be stripped and thoroughly cleaned, to avoid poor oil pressure, which may be caused by salt build up internally.

2 hours submerged in salt water is a long time.

I recently tried reviving an older model that had been under, and everything was packing in on it. In the end I just told the guy to take the boat away, his bill would have been more than the engine was worth.
