d*ck,
It's most likely a 170 Ford marinized by Interceptor but we sure need more information. Welcome to CCfan. Besides pictures of the engine, we'd love some of the Compact too. Tell us more! |

thanks for the response, just bought this boat in sacramento, the seller restores woodies, he thought the engine was original and was a ford dearborn marine... does that sound right? also what size/pitch prop works the best with this 170 engine? |

d*ck,
It is a 170 Interceptor. Regarding the prop, we have several members running the engine so be patient and they will chime in. Off hand, it will be a 12" diameter and I'd say 12 or 13 pitch. how's it run? What WOT (wide open throttle) RPM are you getting and what is the diameter and pitch of the prop now? Nice Compact!! |

Possibly could be a 140 as well? We're running a 12x9 on our 170 ci, 100 hp Mustang. Post some more pics of your Compact. Welcome to the site.

d*ck,
If you don't have a engine manual, check out Marine Engine . com They don't list the straight 6 with a "add to cart" so if you do need the manual, give them a call. |

d*ck,
I just checked and Bruce is correct that the manual is in the reference section. The 144 and 170 are in the same manual as the Y blocks. Thanks Bruce. |

thanks for the feedback all. the prop on it now is one i already had, it barely fit, but after running it in a trial, it touches the hull under power, after researching it on line i discovered it's a 13 x 12 ...wrong prop, but it did run pretty well...30 mph at 3,000 rpm. so i found a 12 x 12 on eBay and ordered it, along with a prop puller. i'll check out the site for a manual for the engine. like a new friend, it takes awhile to figure them/it out...!! i'll post some more pics soon. thanks again, so glad to find fellow boat nuts..

d*ck,
Take a look at this thread before swapping props. Did the restorer put the 13" prop on the boat? |

my local boat shop installed it because i didn't have a puller to take the old one off. i didn't try running it with the prop it came with as the seller said it was the wrong prop and suggested a 12 x 12. thanks for the prop fitting thread, excellent presentation and vital information.

If it's a 170, redline is 4400.

d*ck, In all honesty, I would question a shop that installed that 13" prop especially since you say it actually touched the hull under load. |

hi pete,
had to explore the site to find your name. in response to your last post about the prop size.. they actually told me that it wasn't right when they installed it, but i had to try it out to be convinced. so now with the correct size prop i put it back in the water to find out there is a new problem. it's not getting cooling water to the manifold. it over heated, pegging out the temp gauge before i noticed it, as the exhaust exits under water and one can't tell if there is water in the exhaust gasses or if it's just bubbling hot air. so i pulled it out of the water and put a flushing plunger on the water intake with the garden hose attached and still no water in the exhaust. so i pulled the hose from the downstream side of the impeller where it enters the exhaust manifold, there is water there and water pours back from the exhaust manifold when i removed the hose...??? seems there is something preventing the water from circulating in the water jacket.. any ideas? |

on second thought, maybe the impeller is fried and the water coming out is just hose pressure and not enough volume to make it through the system...i'll check out the impeller tomorrow.

d*ck,
Since the first test run when I'm assuming there wasn't a overheat problem and now when you do have the overheat problem, has the engine been run without water? The RWP (raw water pump) is a rubber flex impeller pump that's water lubricated. When run even briefly without water, the impellers can get chewed up. Check out the impeller. Also, I know the T stats for that engine are real fussy. I'd install a new one. |

d*ck,
Maybe Steve (62wood) will catch this thread and comment on the T stat. I know he fought the stat problem on his 170 even going through several different stats before solving his overheat. I don't remember what stat he ended up with. I'll PM him asking him to comment. EDIT: PM sent to Steve |
