An I/O or inboard with closed cooling can actually out last an outboard; if properly maintained. They cannot be used the same way though because an automotive based engine like the old school GMs were not designed to run at high revs like a 4 stroke or DI 2 stroke can. PS my 28 year old raw water cooled inboard is original.

2014年5月20日 · Drawbacks of inboard vs outboard - inboards are slower than comparable power outboard boats - inboard power plants weigh more than outboard - typically require more draft than similar outboard boats - can't trim an inboard motor - need to be more cautious in shallow waters compared to outboard boat

Inboard vs Outboard Motor My husband and I are going to purchase our first boat and don't know which one is better, an inboard or outboard motor. We are looking at 23 -25 ft. walkaround/cuddy for offshore fishing and family fun.

2010年11月26日 · Diesel inboard vs. outboard maintenance? I've been thinking about going from a 23' cc with a single 200HP yamaha 4S to a larger single yanmar diesel inboard like a Fortier 26. I was wondering about the annual maintenance comparison on the 2 boats.

2016年6月19日 · Then what would I have? - a boat with a 15 year old ($30,000) outboard, or a boat with a brand new ($4,000) motor and outdrive. By the way, to the person who commented, - no one owns a boat (or motor) for thirty years - that is not entirely true. I have a 16' Zodiac Grand Raid with my original 40hp Johnson long shaft I purchased in 1974.

I built my last inboard from scratch, laid the crank in the engine. Ran it offshore for 5 years without a hitch. Numerous trips to 50 miles out... never missed a beat. Straight inboard is the most reliable marine drive ever conceived (short of a jet... that's another debate). Currently building another one. Also the least expensive drive line ...

2010年12月7日 · I switched from a twin outboard 28' boat, to a twin Inboard diesel boat 3 seasons ago. I'm a DIY'er, here's my experience: 1. Maintenance is EASIER on the Diesels, and 99% of it I can do. They are much less complicated. You have a spin off Fuel filter, and a spin off oil filter. The raw water impeller comes off with 4 easy to access bolts.
