Hi Every one,
I have a chance to buy a 1977 33 foot chris craft with twin chevy 350's. Twin V-drives. The boat has a 12 1/2 foot beam. The owner wants $4000.00. He claims every thing is in working order. While we were talking on the phone he mentioned that the top speed was about 15 MPH. That sounded very slow for that kind of power plant. I currently have a 28 foot silverton with a single crysler LM318 and I get up to 20MPH. I know theres 5 more feet and a wider beam but something sounds off here. Any chris craft owners can help me out here?? What do the twin chevy 350's put out in terms of MPH on a 33 footer or similar? The boat is on blocks so I cant take it for a spin. I will be going to look at it next week. Any feedback will be helpfull. Is $4000.00 a good price? I dont know anything about chris crafts. Thanks |

I have owned 2 1970's larger chris crafts and have found them to be heavy and slow. I love the ride and durability. check the exaust-cooling system carefully,many parts are not available. |

Have you checked the props? This boat should run in the mid 20's. RPM's should be around 4200. Parts are indeed plentyful. Join the various Chris sites and you will see. $4000.00 sounds like a excellent deal but does it have a Gen or AC. How much time are on the engines and look at the interior. Start with a compression test first and go from there. Also has it been in fresh water or salt water. Good Luck |

Hey Guys,
Thanks for the replys. The boat does not have a generator it plugs into shore power. Then switches to 4 batteries when underway. It has been in salt water. The boat is in really good condition for a 1977. The interior is very nice and the outside is in good shape. I think I have to make this deal because I have done some research online and I have not been able to find a single chris craft coho from 1974 on going for less than 24,000.00. So to buy this one for $4000.00 even if I had to get new engines (worst case scenario) hiperformer.com sells chevy 350's longblocks for $1300.00 each. I may have gotten lucky here. Will let you guys know. Thanks |

RE:" It has been in salt water"
---and---
"sells chevy 350 longblocks"
1) Using a long block assumes that the parts that live insalt water and take the worse abuse (manifolds and elbows) are still OK.
2) I didn't take the time to track down the exact engine that you referred to, HOWEVER, let me hasten to point out that a generic car or a truck long block chevy IS NOT a good choice for a boat.
That's what MARINE engines are for. Do not fall into the ignorant view that "marine just costs more because they can charge more"... that's NOT true. There are good reasons why marine costs more. |

I have a 72 COHO 33' twin 350's.
It is a heavy large boat.
idea = 6 knot
1500 rpm = 12 knots
2000 rpm = 15 knots
2500 rpm = 20 knots
I can't say beyond that I'm not in a hurry to get the water. And I know the cost to fill the tanks. |

Don't forget to see if one of the engines is a "Reverse Rotation" variety.
These use some different internals to the standard engine.

Thanks for all the replys. I went ahead and purchased the chris craft coho for $3500.00. After some exhaustive research online I have made some very good discoveries that I will share with you all in case anyone is deciding to repower their engines as I have. I purchased two Chevy 350 cubic inch motors from California engines. tel#530-550-0355 Standard rotation $975.00 Reverse rotation $1200.00 They come with marine gaskets and written 5 year unlimited hour warranty. I couldnt find any one to come close to this.
To reply to robert fiero, as the say never assume!!! Upon inspection I discovered that the starboard exhaust manifold and risers were corroded with rust! However I found that Ebasic power.com sells a kit with 2 osco manifolds and 2 risers with a 3 year waranty for $450.00. Thats an amazing deal! The old engines had 2 brand new carburators, 2 brand new starters and 2 brand new altenators. The rockers and rods were all in good shape as were the intake manifolds so practically the whole top of the engine can be reused. So I'm figuring this project from start to finish should cost me about $3500.00 to buy the boat $2175.00 for the new longblocks and probably another $3500.00 in misc. that I havnt figured out yet so for a grand total of approx $10,000.00 I have a 33 foot chris craft in good condition with a brand new power plant with 570HP. Well its never as easy as it sounds!!! good luck all |
