I bought it sight unseen as a parts boat to finish the interior on mine and get some other goodies and switch trailers...and then I saw the boat and decided to sell mine. The block is cracked (OMC 4.3) and am currently shopping for a suitable replacement (in another post). Here are some pics of my $300 boat [img  [/img][img  [/img][img  ][/img][img  [/img]

Not sure how to make those pictures larger, or if I can but there is nothing wrong with the boat...except for a cracked block but everything works on it! [img  [/img]

That's a pre vortec 4.3 Chevy. You can get longblocks for like $500 with warranty. Cheapest engine ever. |

Craigslist, they pop up all the time. Almost all of those parts you can't use but they'd generate lunch money on ebay. http://seattle.craigslist.org/tac/pts/3069281466.html That's a vortec engine, 200hp instead of non vortec 160ish . Vortec 4.3's have 8 intake manifold bolts, Non-vortec have 12. If you have a 12 bolt intake just go ahead and purchase a vortec intake manifold they're like $180 for stock iron ones. See if you can ebay a used aluminum performance one to gain a few ponies. ALSO! I forgot if the vortec had different exhaust bolt patterns or not. Worst comes to worst, you just use your current heads on it. |

Could I use a car/truck engine for a marine application? I was looking at marine blocks...not sure what the difference is in the building process |

Ok so I just read the article about marine engines vs automotive and am being told dont worry about it... hmmmmm. As far as the accessories go, I will use what Ive got so I would just get the long or short block (would prefer long). Anyone know of a good place to look at remanned 4.3's? I am leary of putting a craigslist engine in my boat just because if the engine is already out, I cant run it and therefore am placing a giant question mark in my boat...not a good feeling |

Hey guys thank you so much for the help...this whole stern drive thing is way new to me and foreign. I am an outboard guy so thank you for having patience with seemingly ignorant questions  What is a balance shaft? Is that the shaft that runs through the valley(under the intake manifold), front to back? I could just use the one off of the engine thats in the boat right? I have noticed that the more expensive engines are more expensive because of a warranty (or that's what it seems like)...you think it is worth it to spend more for that peace of mind? Usually I opt out of warranties however, I am usually a little more cautious with boat stuff. Thanks again gents...this is a great site |

A balance shaft helps to stop the engine from shaking. A V8 has the two banks of cylinders in a 90 degree vee and is well balanced without any sort of extra balance shaft. The 4.3L V6 is also a 90 degree vee, basically it is a small block chevy V8 with two cylinders cut off and is not inherently balanced. So they added a balance shaft which is timed to the crankshaft which counters the shaking forces of the engine. I'm not sure where they mounted it in the engine. For a V6, 60 degrees between the cylinder banks is the inherently balanced configuration and doesn't require a balance shaft. The camshaft that operates the valves is in the valley for sure since it is a cam in block pushrod engine. |

I'm the non-warranty kinda guy but that's just me. I do however get insurance  When I purchased my 57" HDTV DLP 4 years ago they tried to sell me this $400 5 year warranty because bulbs would blow out, etc. I said no. Well, 4 years later I'm still on my factory bulb and now they cost $75 if it ever did blow out. Winning. I would never purchase a warranty on an engine like that. 100% of the time they will blame it on something else that caused their engine to break, voiding warranty. Count the intake bolts. 12 = non balance shaft engine non vortec. 8 = balance shaft vortec engine. If you REALLY want the higher HP vortec engine a better route to go would be get the cheap non-vortec 4.3 for $600, then hop on ebay and pick up a set of vortec heads http://www.ebay.com/itm/4-3L-VORTEC-HEADS-REMANUFACTURED-10235772-/320918316237#ht_500wt_1139 and a vortec intake manifold http://www.ebay.com/itm/4-3L-4-bbl-GM-MerCruiser-VORTEC-Intake-Manifold-1996-Later-/280897409215?pt=Boat_Parts_Accessories_Gear&hash=item4166ca50bf&vxp=mtr#ht_2464wt_1116 and a marine 4bbl carb calibrated for the 4.3 http://www.holley.com/0-80492.asp And in the process of fixing your boat.. for $1500 worth of parts you went from 170hp to 220+ Throw a cam in the mix and you're looking at 250+ hp. http://www.ebay.com/itm/Crane-Cams-High-Performance-Cam-Chevrolet-4-3L-90D-V6-92-02-488-509-/140719524382?pt=Motors_Car_Truck_Parts_Accessories&hash=item20c3898a1e&vxp=mtr#ht_3857wt_888 More HP then a standard V8. God I love the 4.3 AND Still cheaper then a factory longblock from a "marine" dealer

Ok yeah that balance shaft makes sense...especially for that angle of the V. I just though that was the job of the dynamic damper. I was googling that balance shaft and a result came up with another website and this guy was saying he left it off because it robbed HP?? DOesnt make sense to me--if anything it should help the power. Yeah and besides, I think that the 4.3 is a good engine design so I dont really foresee any issues. The engine that is in the boat has a four barrel quadrajet on it...as for the heads, I could swing that! Do they make H.O exhaust for marine engines? I just want to get an engine in the boat but, I like pepping things up a little, cant leave anything stock! So, to take the motor out, I could disconnect fuel line, water, wire harness and controls, unbolt from transom assembly and unbolt engine mounts and out she comes? Seems easier than taking an engine out of a truck. |
