Is a vetus VH 4.65 a good and reliable Engine
The Hyundai H100 2.6D D4BB is the base Engine
which Vetus then marinize. The Hyundai is known and proven simple Diesel
engine and is widely used in a lot of Pickups, busses, Transporter, Vans, Mini Trucks especially in 3rd world countries due to simple,robust,easy to repair.
The Vetus too or did they screw up the marinization? Also you will never have to do a overhaul
of the engine, I get a low mileage D4BB for 500$ and a new for below 3000$ so no overhaul
makes sense as a good used or even a new block and head
is cheaper then rebuild
You can also easily tune the Vetus VH4.65 =65hp to a VH4.80=80hp. Only 3 differences: bigger diameter exhaust elbow
, bigger impeller pump
and rev limiter is raised from 3000RPM to 4000rpm. The additional 15hp just comes from reving higher, there is no difference till 3000rpm between the two engines.
But the 4.80 has a different gearbox
ratio to account for that. I assume if I keep the 4.65 gearbox
ratio then engine will rev higher but the extra 15hp won‘t change anything like top speed.
Can I get around that by buying
a different folding prop with eg different pitch
Maybe not 100% like original 4.80 but if it’s 90% is ok for me. I am a total noobie on that gear
ratio and Propeller
need to be changed anyhow and the fixed standard prop i want to replace by a folding prop. so tuning/modifying it is just the price
difference from 4.65 to 4.80 parts
but it won‘t make sense if I need to change the gearbox to get the benefits of the extra 15hp.
