Engine question
I am looking at a Cruisers Inc 32' express. It has twin 350 chevy
engines. One engine is new and the other has 1000 hours. The boat itself is in very good shape for a 1989. I'm sure the old engine will need replacing soon. If I buy it, I was thinking I would build two 388 c.i. engines. This is a 350 block with the 400 crank. I get the torque of the 400 with the reliability of the 350. I would assume the boat should plane a little easier. Any thoughts? Stu |

The boat itself 1000 hrs isn't a lot of run time but being a '89 there maybe issues with block rust out if it is raw water cooled and has been used in salt water. From my experience with very early Chev. to Marine convertions, the crank marine versions had fordged cranks and the cams were for solid lifters rather than hydraulic. If I were you, I would run it with the engines as-is until the old engine requires replacement. By then I think you will agree that it is best to stay with the original size since everything will be interchangeable between old and new. -- My opinion and experience.

Engine question
I am not sure about the spec's of the 388 but I have never been much of a
Chevy man. The big question I have is you did not mention the spec's of the outdrive or the inboard. More torque means more twisting on the drive components that may or may not be able to take it. Need to check their capability. Your upgrade to a 388 sounds logical. But If it is that logical why doesn't Chevy offer that engine as an option in the truck or car. The increased stroke means that the compression ratio will change so I would guess that new pistons and rods are required to get back to something reasonable? When I am at the dock I really don't care if the engine starts or not. I can have lots of fun there and fix the problem tomorrow. When on the water I want ultimate reliability on being able to get back home. That's just me. Everybody wants more horsepower and torque but there are a few things that an owner can do to help performance. 1) Remove as much excess weight as possible. You want to enjoy life but you don't need to duplicate the living room furniture on the boat. Do you need every kitchen appliance?2) How is the trim when moving - is it optimum? 3) Are the props right?, and 4) is the bottom and props clean and free of fouling? Also, read the specs on your boat and/or similar ones. It seems like going from 500 HP to 600 HP only add a few MPH at the top end. The view may not be worth the climb. I have heard folks say that a gas engine will last ~2000 hours. Its a function of the running at high HP vs the requirements of a car. One engine probably failed for some reason and was replaced at 1000 hours. It would be nice to know why. Have fun boating and good luck with your rebuilds.

Engine question
As luck would have it (for me), the old engine lost a rod bearing on our
test drive. The owner is having it repaired. Now it makes no sense for me to have engines built. Are there any Cruisers owners out there that can give me info on the planing speeds etc for the 32' esprit? I do know the boats have a good reputation for build quality. Pending the survey, I will buy the boat. This will be my first foray into owning a larger powerboat. All my previous boats have been sailboats, except for small powerboats. The only reason we are making the switch is I can't find a home for our 42' trimaran in the southern California area. Stu |

Stu Saw your later about the other one blowing up, but recalled that a dockmate changed his gearing up and switched to larger props. Significant improvement in all around performance and economy with the same engines. That may work better for you than anything else. -- Jere Lull Xan-a-Deux ('73 Tanzer 28 #4 out of Tolchester, MD) Xan's Pages: http://members.dca.net/jerelull/X-Main.html Our BVI FAQs (290+ pics) http://homepage.mac.com/jerelull/BVI/ |

Changing the gears and props would be an option. Since the boat will have a new engine, I think I'll wait and see how it runs. I have a bit of a learing curve ahead of me just to figure everything out about the boat. I do like to tinker though... |
