Did Mercruiser make a mid 70's model 188 hp with a ford 351?
I have broken down the motor and i believe it has 351 heads. any help??

Probably a 302 with 351 heads. Measure the bores

They are listed in manual 1 and 2 :255" ? What is the spread of the intake manifold bolts left to right. 8ish is a 302 and 9 ish is a 351

I had a 1978 Century with an OMC I/O and the engine was a 351M. I'm not a Ford guy but I believe they had a 351 Windsor, a 351 Cleveland, and a 351 Michigan (hence the"M"). That was cast into the intake manifold. Served me well for many years. Can't vouch for the 351C or 351W in boats, but I can vouch for the 351M.

Ford engines used by Merc with stern drives, and their designations.

'888'. 302 engine with 351 heads, 2 bbl carb. 188hp 1972-1976
'225'. 302 engine with 351 heads, 4 bbl carb. 225hp 1974
'255'. 351 engine, 4 bbl carb. 255hp 1973-1974. (only with TR drive)

In 1970 to 1972 they also used a 302 coupled to hydraulic or electric gearboxes, not seen since (thankfully!) and that engine was rated at 215hp.

Similarly configured Ford engines were also used as MIE (inboard/ski). Mercruiser ended their association with Ford in 1976.

Okay so it is the 302 with 351 heads. I had a not so good compression test and have broken the motor down. So what would be the rebuild kit i would need to order?

 

[achris]

Gasket kit I would get from FelPro. If it's new pistons you need, try one of the aftermarket on-line shops.

go to your local engine builder and have them order the parts.
