Tony,
do a search on this forum, just enter mercruiser 1.7 in the box. You will find lots of posts relating to this engine. A number describing problems.
Do tell us what problems you have had.

Peter

mercruiser 1.7

We have had the engine for 4 and a half years in a Humber rib and so far we have had 3 startermotors, 1 alternator, 1 new turbo unit. we took it out for it's first run on easter monday and afteronly 6 miles the overheat warning came on, it had boiled up and chucked the cooling fluid all over the engine, it was refilled , it did it again so we came back in very slowly.

It is now in the hands of the area agents who have stripped it down to find that the head is damaged and the cam box is warped, estimated costs of repair 4000, this engine has only done 600 hours, we are waiting responce of Barrus Marine the importers

Just replied to another post and remembered this one.

On 355hrs thus far, faults have been:

1. killcord switch failure and replacement

2. Water pump bearings replaced under warrenty (belt too tight)

3. Coolant weeping through filler cap vent (see seperate thread)

Like the engine and it is worked very hard in a workboat application, so we'll see what happens at 600hrs. Bad luck on your one though, sounds like a lemon.

Engine replaced at 18 Months old due to oil cooler failing and filling the engine with sea water the engine objected and blew all oil seals then droped rpm to 1400 but kept going for 2 hours ????? Lubing on salt water

Third starter motor (100.00 from Vauxhall dealer but keep drive pinion as it has 1 less teeth on it. could be even less from a motor factor)

Gimbal bearing replaced. Should have been replaced with engine

Glow plug kit fitted to help starter last a little longer

understand the D3 is as bad

Hi If this thread is still being looked at I have had a 1.7 for nearly 5 years.
I blown turbo replaced under warrenty
After just over 4 years (approx 450hrs) a holed piston,An early problem with I,m told a faulty spray pattern on the number 3 piston;.
The engine was replaced free of charge out of warrenty now badged Cummins.
My advice would be keep having dealer services and don't be afraid of demanding a new engine.
Please contact me for further discussion if you need to
The unit and leg is now for sale(90hrs) making way for more horsepower.(offers)??
Regards
Jon Adlard
